getcalc.com's Arithmetic Progression (AP) calculator, formula & workout to find what is the sum of first 50 odd numbers. 1 + 3 + 5 + 7 + 9 + . . . . + 99 = 2500
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 .
Solution. First 50 odd natural numbers are: 1, 3, 5, 7, ... First term (a) = 1. Common difference (d) = 3 – 1 = 2. Now, S n = n 2 2 a + n - 1 d S 50 = 50 2 2 a + 50 - 1 d = 25 2 1 + 49 2 = 25 2 + 98 = 25 × 100 = 2500. Hence, the sum of first 50 odd natural numbers is 2500. Suggest Corrections. 77.
