## How to Find Sum of First 360 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 360 by applying arithmetic progression. It's one of an easiest methods to quickly find the sum of any given number series.
step 1 address the formula, input parameters & values.
Input parameters & values:
The number series 1, 2, 3, 4, . . . . , 359, 360.
The first term a = 1
The common difference d = 1
Total number of terms n = 360

step 2 apply the input parameter values in the formula
Sum = n/2 x (a + Tn)
= 360/2 x (1 + 360)
= 129960/2
1 + 2 + 3 + 4 + . . . . + 359 + 360 = 64980

Therefore, 64980 is the sum of positive integers upto 360.
