WitrynaSolution. Given: First term ( a) = a 1 = 1. n th term = a n = 20. Sum of n terms = S n = 399. Now, a n = a + n - 1 d ⇒ 20 = 1 + n - 1 d ⇒ n - 1 d = 20 - 1 ⇒ n - 1 d = 19... 1 S n = n 2 2 a + n - 1 d ⇒ 399 = n 2 2 1 + 19 From 1 ⇒ 399 = n 2 21 ⇒ 798 = 21 n ⇒ n = 798 21 ⇒ n = 38. Hence, the value of n is 38. Suggest Corrections. Witrynan t h term of an A.P. is a n = a 1 + n-1 d where a 1 = first term, d = common difference. Given, a 1 = 1, a n = 300. a n = a 1 + n-1 d 300 = 1 + n-1 d 299 = n-1 d n-1 = 299 d. Now, given that common difference is integer and also n-1 will be an integer. So, d = 23 or 13. If d = 23, ⇒ n-1 = 13 ⇒ n = 14. It is impossible as, 15 ≤ n ≤ 50 ... jordan cottage broadstairs
