Thank you sooo much. Just watching the first 1min 45sec has allowed me to continue with my homework. My calc professor assumes way too much and skips information as if we were born knowing calc already.

i thought r was in abs value sign how is it -(1/2) then?

[xToxicInferno]

@naughtydevil02

No. When the absolute value of r is less than (<) 1 then the infinite series has a sum. So:

The ratio of that series is: -(1/2). It so happens that the absolute value of -(1/2) is less than 1, so you CAN find the sum of the series. If the absoulte value of the ratio is is greater than 1 then the answer is infinitely big.

You're a lifesaver! My final is in a few days, and I could not figure out how to do this. But now, thanks to you, it all makes sense! Thank you so much!
