How to Find Sum of First 130 Natural Numbers?
The below workout with step by step calculation shows how to find what is the sum of natural numbers or positive integers from 1 to 130 by applying arithmetic progression. It's one of an easiest methods to quickly find the sum of any given number series.
step 1 Input parameters and values:
The number series 1, 2, 3, 4, . . . . , 129, 130.
The first term a = 1
The common difference d = 1
Total number of terms n = 130
step 2 apply the input parameter values in the formula
Sum = n/2 x (a + Tn)
= 130/2 x (1 + 130)
= 17030/2
1 + 2 + 3 + 4 + . . . . + 129 + 130 = 8515
Therefore, 8515 is the sum of positive integers upto 130.
