Answer 2

Step-by-step explanation:

The sum of first n terms of an AP is 5n n2 find the nth term of the AP

Let a be the first term and d be the common difference. We know that, sum of first n terms = Sn = [2a + (n − 1)d] It is given that sum of the first n terms of an A.P. is 5n − n2. ... Thus, nth term of this A.P. is 6 − 2n.
