KnowledgeBoat · Accepted Answer

Given, A.P. : 11, 8, 5, 2, ....... a = 11 d = 8 - 11 = -3 Let nth term of the A.P. be -148. Tn = -148 ⇒ a + (n - 1)d = -148 ⇒ -148 = 11 + (n - 1)(-3) ⇒ -148 - 11 = (n - 1)(-3) ⇒ -159 = (n - 1)(-3) ⇒ = n - 1 ⇒ n - 1 = 53 ⇒ n = 53 + 1 ⇒ n = 54. Hence, option 2 is the correct option.
