In an arithmetic progression, if a = 2n +1, then the common difference of the given progression is

In an arithmetic Progression T_n=3n-1 , then common difference is:

The sum of first n terms of an arithmetic progression is 270. If common difference of the arithmetic progression is 2 and the first term is an integer, then number of possible values of n gt 2 is

If the n-th term of an arithmetic progression is 5n+3 , then 3rd term of the arithmetic progression is

If the n-th term of an arithmetic progression is 5n+3 , then 3rd term of the arithmetic progression is

If the n-th term of an arithmetic progression is 5n+3 , then 3rd term of the arithmetic progression is

(a) The nth term of a progression is (3n + 5) . Prove that this progression is an arithmetic progression. Also find its 6th term. (b) The nth term of a progression is (3 - 4n) . Prove that this progression is an arithmetic progression. Also find its common difference. (c) The nth term of a progression is (n^(2) - n + 1). Prove that it is not an A.P.
