WebThe given A.P. is 6, 13, 20, …, 216. Let n be the number of terms, Common difference, d = 13-6 = 7. First term, a = 6. Last term, a n = 216, a n = a + (n-1)d. ⇒ 216 = 6 + (n-1)7. ⇒ 210 = (n-1)7. ⇒ 30 = n-1. ⇒ n = 31(Odd) So, we have to find a 16 for this A.P. a 16 = 6 + (16-1)7. ⇒ a 16 = 6 + 15 × 7. ⇒ a 16 = 6 + 105. ⇒ a 16 ...
