In an A.P., given a = 8, a n = 62, S n = 210, find n and d.

Given, a n = 62 By formula, a n = a + (n - 1)d Substituting values we get : ⇒ 62 = 8 + (n - 1)d ⇒ (n - 1)d = 54 ........(1) Given, S n = 210 By formula, S n = Substituting values we get : Substituting value of n in equation (1), we get : ⇒ (6 - 1)d = 54 ⇒ 5d = 54 ⇒ d = . Hence, n = 6 and d = .
