How to Find the Sum of First 50 Odd Numbers?
The below workout with step by step calculation shows how to find what is the sum of first 50 odd numbers by applying arithmetic progression. It's one of the easiest methods to quickly find the sum of given number series.
step 1 Address the formula, input parameters & values.
Input parameters & values:
The number series 1, 3, 5, 7, 9, . . . . , 99.
The first term a = 1
The common difference d = 2
Total number of terms n = 50
step 2 apply the input parameter values in the AP formula
Sum = n/2 x (a + Tn)
= 50/2 x (1 + 99)
= (50 x 100)/ 2
= 5000/2
1 + 3 + 5 + 7 + 9 + . . . . + 99 = 2500
Therefore, 2500 is the sum of first 50 odd numbers.
