The sum of odd numbers formula is S n = n/2 × [a + l] where 'a' is the first odd number, 'l' is the last odd number and 'n' is the number of odd numbers present in that range. Another formula to calculate the sum of first n odd numbers is S n = n 2 .
First 50 odd natural numbers are: 1, 3, 5, 7, ... Hence, the sum of first 50 odd natural numbers is 2500.
18 Αυγ 2024 · Let's use the formula for the sum of an arithmetic series, Sn = n/2 × (a1 + an ) Sn is the sum of the series, n is the number of terms in the series = 50. a is the First odd number = 1. d is the common difference = 2. Sn = 50/2 × (2×1+ (50−1)×2) ⇒ Sn = 25× (2+98) ⇒ Sn = 25×100.
