## How to find the Sum of Natural Numbers from 50 to 75?

The below workout with step by step calculation shows how to find what is the sum of natural numbers or positive integers from 50 to 75 by applying arithmetic progression. It's one of an 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 50, 51, 52, 53, . . . . , 74, 75.
The first term a = 50
The common difference d = 1
Total Number of terms n = 26

step 2 apply the input parameter values in the formula
Sum = n/2 x (a + Tn)
= (26/2) x (50 + 75)
= (26 x 125 ) / 2
50 + 51 + 52 + 53 + . . . . + 74 + 75 = 1625

Therefore, 1625 is the sum of positive integers between 50 and 26.
