In an arithmetic progression,if `S_(n)=n(5+3n)` and `t_(n)=32` ,then the value of n is
[Note: S(n) and t(n) denote the sum of first n terms and n th term of arithmetic progression respectively.]

In an arithmetic progression, if S_n = n(5+3n) and t_n = 32, then the value of n is [Note : S_n and t_n denote the sum of first n terms and nth term of arithmetic progression respectively.] (A)4(B)5(C)6(D)7

If S_(n)=n^(2)a+(n)/(4)(n-1)d is the sum of the first n terms of an arithmetic progression, then the common difference is

The absolute value of the sum of first 20 terms of series, if S_(n)=(n+1)/(2) and (T_(n-1))/(T_(n))=(1)/(n^(2))-1 , where n is odd, given S_(n) and T_(n) denotes sum of first n terms and n^(th) terms of the series

Let S_1 be the sum of first 2n terms of an arithmetic progression. Let S_2 be the sum first 4n terms of the same arithmeti progression. If (S_(2)-S_(1)) is 1000, then the sum of the first 6n term of the arithmetic progression is equal to :

If S_n=an^2+bn+c where c ne 0 and S_n denotes the sum to n terms of a series, verify whether the series is arithmetic.

Let S_(n) denote the sum of first n terms of an A.P.If S_(2n)=3S_(n), then find the ratio S_(3n)/S_(n)

Suppose the sum of the first m teams of a arithmetic progression is n and the sum of its first n terms is m, where mnen. Then the dum of the first (m + n) terms of the arithmetic progression is

If the sum of n terms of a series is S_(n)=n(5n-3) find the n^(th) term and p^(th) term

If the sum of 'n' terms of an arithmetic progression is S_(n)=3n +2n^(2) then its common difference is :
