In the A.P. 8, 13, 18, ......., the n th term is 83, then n is equal to : 1. 14 2. 16 3. 13 4. 15

In the A.P., First term (a) = 8 Common difference (d) = 13 - 8 = 5. By formula, ⇒ a n = a + (n - 1)d Substituting values we get : ⇒ 83 = 8 + 5(n - 1) ⇒ 83 = 8 + 5n - 5 ⇒ 83 = 5n + 3 ⇒ 83 - 3 = 5n ⇒ 80 = 5n ⇒ n = = 16. Hence, Option 2 is the correct option.
