If the sum of 'n' terms of an arithmetic progression is `n^(2)-2n`, then what is the `n^(th)` term?

If the nth term of an arithmetic progression is 2n-1 , then what is the sum upto n terms?

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

If S_n denotes the sum of first n terms of an arithmetic progression and an denotes the n^(th) term of the same A.P. given S_n = n^2p ; where p,n in N , then

If S_(n) denotes the sum of first n terms of an arithmetic progression and an denotes the n^(th) term of the same A.P.given S_(n)=n^(2)p; where p,n in N, then

If the ratio of the sum of n terms of two arithmetic progressions is (3n+8):(7n+15) then the ratio of their 12th terms is :

If the n^(th) term of an arithmetic progression is (2n-1). Find the 7^(th) term.

If the n^(th) term of an arithmetic progression a_(n)=24-3n , then it's 2^(nd) term is

If the n-th term of an arithmetic progression a_(n) = 24 - 3n then its 2nd term is
