In an Arithmetic Progression, if `a = 28, d = -4, n = 7`, then `a_n` is:

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 log_(l)x,log_(m)x,log_(n)x are in arithmetic progression and x!=1, then n^(2) is :

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.]

If T_(54) is an fifty fourth term of an Arithmetic Progression is 61 and T_(4) is fourth term of an same Arithmetic progression is 64, then T_(10) of that series will be : ( T_(n)=n^("th ") term of an A.P.)

If T_(54) is an fifty fourth term of an Arithmetic Progression is -61 and T_(4) is fourth term of an same Arithmetic progression is 64, then T_(10) of that series will be ( T_(n) = n^("th ") term of an A.P.)
