Sequences 1: Number Sequences

[BobT427]

1.Number sequences such as 1,7,8,15,23,?,61

Can anyone tell me what the answer is to this? Could u please explain how to do this? TY!!

[BobT427]

@BobT427 i see niggas --- i luv this guy

[Anti0Not]

@BobT427 @BobT427

1+7=8, 8+7=15,15+8=23,23+15=(38?),38+­23=61

[Parthematics]

Did anyone else notice that the year that Fibonacci published "The Book Of Squares" in the year 35^2 ?

[Kazekage121]

sometimes when i poop water splashes my butthole

[magnusblz3]

He's passionate about teaching, you can tell. Which is very rare in schools.

[TheMathstat]

wao thanx sir u really give me the new idea between sequences of noms wao u r fine and cute also

[markdhen]

now i understand how to identify it.. wew..

[jackthelad101]

i love this guy!

[sunnyXsideXcyanide]

if you have a chance you should check out my short vid. yutube.com/watch?v=_w883aiqKHw which is a 3 minute video i made showing how sacred geometry is the backbone to almost all of our historic, present and way ancient religious and everyday symbols.

[bloodredorion]

I really like your videos, keep it up!

[SlimJ1992]

@lakai0or0die i just wanted to clear it up for the ones who might be confused, and strange that 33 people found it helpful.

[LeBadman]

Someone stop the chalkboard skreaching!!! Grah, it's annoying.

[plasticbudgie]

Absoloutly great thank you sir.

[desperategirl01]

nice

[oppressivedrummer]

This dude is awesome, thanks!

[QUANTA9]

We learned this while we were 13...

[MyAccountman]

I noticed what he was talking about while he was writing the numbers, so cool!

[MaraimH]

thank you so much for posting this :)

[Strugamanoo]

Do u know what squares mean? 1times 1=1, 2 times 2=4, 3 times 3=9, 4 times 4=16...

[billygundum]

lost...

how do we get from 1 to 4 etc.?

brake it down please, baby talk even.

[JEREX101]

@billygundum add 3

[slug1597]

the internet is a crazy thing!

[sexy19081995]

dis guy is an idiot...afta 5square its six square not sixteen square....buddha gaddha hai saala....

[GeneralOJB]

@sexy19081995

He's not an idiot. He's very clever, and a brilliant teacher. It was just a simple mistake. He added the 'teen' on accidentally.

You're an idiot if you can't tell the difference between lack of intelligence and a slip of the tongue.

[bubbzipp]

@sexy19081995 just....... g.t.f.o.

[odiggler]

1 + 1 = Cat

[psychofish25]

does it have anything to do with the derivative of x^2... 2x?

[MrSequence1]

lol i love sequences! tell me also about the hypotenuse plz

[ncharles93666]

Not 1+1, just 1 by itself. 1 squared. There is no number to add to 1 until the second number in the sequence of squares, when we add 1 and 3.

[fernades45]

@ncharles93666 was kidding dude

[michaeljimpogi23]

you're teaching clearly!!:))

[edwardtarte]

I too am a math teacher. What's in this video can also be illuminated beautifully in a geometric way: Draw 1 little marble. Then in an L-shape add 3 marbles, forming a 2-by-2 square of 4. Then in a larger L-shape add 5 marbles, forming a 3-by-3 square of 9. Then in a larger L-shape add 7 marbles, forming a 4-by-4 square of 16. Then in a larger L-shape, add 9 marbles, forming a 5-by-5 square of 25. And so on. Math becomes all the more beautiful when one branch of math illuminates another.

[mortinus00]

I have been stumped for years, constantly being annoyed with all the little 'rules' that people tell you to follow, but no reasons or explanations on HOW WHY IS. This simple explanation of marbles has given me a complete understanding of squares..visually! I don't know why but I really need this level of visual comprehension of concepts. Thank you!!

[Adastra14]

and so simply put.

i wish you were my teacher back in school. i would have loved maths.

we had some short old hag with no sense of humanity what so ever.

thanks for the vid !

[Tubbs3695]

I have a question on my homework and it says the third and fourth terms of a sequnce are 26 and 40. ladeladeladedah. It says something about a constant 4.  What is that. Can anyone help me please. Send me a message. please.

[sonofagunM357]

@ 2:54 What a Coincidence! Its things like those that drew me AWAY from mathematics.

[DJxSGGxNeo]

I not new to any of this, well I had my break of this series some time ago, I tried to find out every thing out at once instead of letting it just come to me, and now I see your videos and some others and I think I will try to understand the numerology at a slower pace.

[Tonty53]

Interessante

[ODBastardW]

wow incredible. i know some math but this thing must have slipped. how is this even possible? amazing!

[fidoda007]

Can it be used as a way to calculate prime numbers?

[gcash2009]

i dont know why but ive been doing stuff like that when i was 9 or 10 years old, but nobody arround me understood about mathematics and noticed what i just had discovered at my very young age... so my familiy just thought i like to count weird numbers... a couple of years later in school i found out what ive been doing

[cbassimhs04]

at 1:09 he says 16 squared lol

[johninajet]

i want his mathematical babies

[elementoxygen]

I love your videos. I've learned so much from you!

[XFaGgYX]

uooooooo...

cool^.^

[JohnnyBleu]

Haha, cool. I came to this conclusion while collecting garbage in an office building last year. I'm only 800 years late.

[BrocWorst]

Cool thank you!

[0103303]

Squares = 169, 196, 225, 256

[SlimJ1992]

haha mistake at 1:07 it is 6^2 not 16^2

[0103303]

yes... 225=15^2

[djjoelroche]

@SlimJ1992

As Fibonacci said, he's only human! :) How true lol

[mohdafaquekhan]

@SlimJ1992 sir you tought very well and i like your way of teaching 4RM THIS WAY EVERY thing about base of sequence become clear ''''HIRA NAAZ;;; FROM PAKISTAN

[Indogyearsimdead]

@SlimJ1992 No, actually he's right and your wrong. He wrote 16 comma the square of 4. From the logical progression of squares 1,2,3,4,5 etc.

[tanton1]

Thats numberwang!

[JillLovewood]

ARGHHHHHH..i hate number sequences...it is very complicated!!!

[notimelikenow08]

It seems that the sequence of squares is odd, even, odd, even, and so on.

[stubbedtoe9]

It is. This can be seen as a result of the fact that even + odd = odd and odd + odd = even.

[itsapickerspick]

a mathematical explanation:

First n odd numbers: 1,3,5,7,9,...,(2n-1) where 2n-1 is nth odd number

Note that sum of n natural numbers = 1+2+3+...+n=n*(n+1)/2

Now

Sum of n odd numbers = 1+3+5+..+(2n-1) = (2*1-1)+(2*2-1)+(2*3-1)+...+(2­*n-1) = 2(1+2+3+..+n) - (1+1+1+...n times) = 2*Sum of n natural numbers -n=2*[n*(n+1)/2] - n=n*n+n-n=n^2 =Square of number n

And hence the sequence observation in the video!!

[roflroflomgomg]

(stfu)^2

[Color1377]

5 squared... next is 16 squared

[Nanumir]

16^2?

[themarman]

This is such a great video sequence. Truly appreciate it, please keep making more.

cheers

[grimcath]

Dude that is awsome, this will be very helpful in math next year XD

[grimmravner]

WOW, I have learned more about math in these short videos than 5 years of public education.

[RyanChristianson]

and your parents didnt have to pay taxes either.

[chopperhead2011]

hahaha

[TonyZayasEDS]

@grimmravner Diddo, they need to clone this caring, insightful. professor and place him in every school in the country/ Maybe we'll stop ending up in 8th position at the World Math Competition.

Namaste (The light in me; honors the light in you)

[grande1899]

@grimmravner That's because American education sucks.

[cokezero200]

spot on dude

[JEREX101]

@grimmravner yea........very stange huh?.........yep....i agree......could u imagine learning five yrs of teaching evryday in one week.......lol....thanks to these short vids...maths is my worst problem in skool....but these short vids is making it easy for me lol....

[Yodovannn]

@grimmravner well. this guy is interested to share his knowlege. and public education ...

[mugsyjeff]

@grimmravner I agree, lol. I wish this man was my maths teacher in high school, i might have understood it

[iggy4323]

What year level is this taught to in America?

[chopperhead2011]

Depends on the school and the person's intelligence. I'm 15, and I do not ever remember this particular sequence being discussed - though I think this is cool!!!

[abbesieyes]

There are 16 Vedic Mathematical Sutras, and one of them is known as "Digital Compression" which simply means we "add the digits", thus when we look at the Fibonacci Numbers: 1, 1, 2, 3, 5, 8, we notice that these are all single digits, which is our aim to express all the following digits as singularly reduced digits.

[opinionhead444]

You may already know this. Fibonacci discovered those facts in 35th-squared year after the initiation of the Common Era. Even further, the digits of 35 are consecutive odd which appear in your first sequence.

It's stuff like that made me obsessive-compulsive for number theory.

[abbesieyes]

Everything in the universe is based on the number string 1 through 9 originating and recursing into the fullness (which the West calls 'zero'), in various relations...so your contention is not all that mind blowing.

But if it got you interested in logos and number theory...outstanding.

Much MaHalo's Braddah!!
