How to find the Sum of Natural Numbers from 50 to 100?

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 100 by applying arithmetic progression. It's one of an easiest methods to quickly find the sum of given number series.
step 1 Input parameters and values:
The number series 50, 51, 52, 53, . . . . , 99, 100.
The first term a = 50
The common difference d = 1
Total Number of terms n = 51

step 2 apply the input parameter values in the formula
Sum = n/2 x (a + Tn)
= (51/2) x (50 + 100)
= (51 x 150 ) / 2
50 + 51 + 52 + 53 + . . . . + 99 + 100 = 3825

Therefore, 3825 is the sum of positive integers between 50 and 51.
