Question

Assertion(A): If Sn is the sum of the first n terms of an AP, then its nth term an is given by an = Sn – Sn – 1 Reason (R): The 10th term of the A.P. 5, 8, 11, 14, ………………. is 35.

Assertion: If the sum of the first n terms of an AP is Sn = 3n² − 4n, then its nth term is an = 6n − 7. Reason: The nth term of an AP whose sum to first n terms is Sn, is given by an = Sn – Sn – 1.
