In an a.p. t10 57 and t15 87 then find t21

WebLet the number of terms in the A.P. be n. Then, t n = 101 Since t n = a + (n – 1)d, 101 = 1 + (n – 1) (2) ∴ 101 = 1 + 2n – 2 ∴ 101 = 2n – 1 ∴ 102 = 2n ∴ n = 102 2 = 51 Now, S n = n t t n n 2 ( t 1 + t n) ∴ S 51 = 51 2 ( 1 + 101) = 51 2 ( 102) = 51 × 51 = 2601 ∴ The sum of odd natural numbers from 1 to 101 is 2601. WebWe know that the formula for the nth term is t n=a+(n−1)d, where a is the first term, d is the common difference. It is given that the nth term is t 15=55 and the first term is a=13, …
