 Hi and welcome to the session. Let us discuss the following question. The question says write the first five terms of Each of the sequences in exercises one to six moves in a terms are Six part as a n is equal to n into n square plus five by four Let's now begin with the solution given in a term is n is equal to n into n square plus five By four since we need to find the first five terms therefore we will put n as One two three four and five By substituting n as one in the nth term We get A1 is equal to 1 into One square plus five by four. This is equal to one into Six five four and this is equal to six five four and six five four is equal to three by two By substituting n as two in the nth term we get A2 is equal to two into two square plus five by four This is equal to two into four plus five By four and this is equal to two into nine by four and this is equal to 18 by four and this is equal to nine by two By substituting n as three we get a three is equal to three into three square plus five By four and this is equal to three into nine plus five by four and this is equal to three into 40 by four and this is equal to 42 By four and this is equal to 21 by two As substituting n as four we get a four is equal to four into Four square plus five by four. This is equal to four into eight plus five by four and this is equal to Sorry four square is equal to 16 So this is equal to four into 16 plus five by four and this is equal to 21 I substituting in as five we get a five is equal to Five into five square plus five by four and this is equal to five into 25 plus five by four and this is equal to five into 30 by four and This is equal to one fifty by four and this is equal to seventy five by two hence the required terms are three by two nine by two 21 by two 21 and 75 by two This is our required answer. So this completes the session. Bye and take care
