WebAs we have discussed earlier, we cannot evaluate each and every term of the AP to determine these specific terms (such as T 20, T 45, T 90, T 200, etc).Instead, we must develop a relationship that enables us to find the n th term for any value of n. To do that, consider an AP whose first term is 'a' and the common difference is 'd'.

WebMedium Solution Verified by Toppr We 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, therefore, t n=a+(n−1)d ⇒55=13+(15−1)d ⇒55=13+14d ⇒14d=55−13 ⇒14d=42 ⇒d= 1442=3 Hence, d=3 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.
