## How to Find Sum of First 700 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 700 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, . . . . , 699, 700.
The first term a = 1
The common difference d = 1
Total number of terms n = 700

step 2 apply the input parameter values in the formula
Sum = n/2 x (a + Tn)
= 700/2 x (1 + 700)
= 490700/2
1 + 2 + 3 + 4 + . . . . + 699 + 700 = 245350

Therefore, 245350 is the sum of positive integers upto 700.
