Question

The 8th term from the end of the A.P. 7, 10, 13, ..., 184 is: 1. 157 2. 160 3. 163 4. 166

KnowledgeBoat · Accepted Answer

Given, a = 7 d = 10 - 7 = 3 an = 184 We know that, ⇒ an = a + (n - 1)d ⇒ an = 7 + (n - 1)(3) ⇒ 184 = 7 + (n - 1)(3) ⇒ 184 - 7 = (n - 1)(3) ⇒ 177 = (n - 1)(3) ⇒ = (n - 1) ⇒ n - 1 = 59 ⇒ n = 59 + 1 ⇒ n = 60. The 8th term from the end is the (n - 8 + 1)th term from the beginning. = 60 - 8 + 1 = 53. ⇒ a53 = 7 + (53 - 1)3 = 7 + (52)(3) = 7 + 156 = 163. Hence, option 3 is the correct option.
