Is 402 a term of the sequence : 8, 13, 18, 23, ........?

Question

KnowledgeBoat · Accepted Answer

Since, 13 - 8 = 5, 18 - 13 = 5 and 23 - 18 = 5. Hence, the series is an A.P. with common difference = 5. We know that n^th term of an A.P. is given by, ⇒ a_n = a + (n - 1)d, where a is the first term. Let 402 be n^th term, ⇒ 402 = a + (n - 1)d ⇒ 402 = 8 + (n - 1)5 ⇒ 402 = 8 + 5n - 5 ⇒ 402 = 5n + 3 ⇒ 399 = 5n ⇒ n = Since, the no. of term cannot be in fraction. Hence, 402 is not a term of the sequence.
