## What is the sum of n numbers?

The sum of n terms of AP is the sum(addition) of first n terms of the arithmetic sequence. It is equal to n divided by 2 times the sum of twice the first term – ‘a’ and the product of the difference between second and first term-‘d’ also known as common difference, and (n-1), where n is numbers of terms to be added.

## What is the sum of first n numbers?

Sum of the First n Natural Numbers. We prove the formula 1+ 2+ … + n = n(n+1) / 2, for n a natural number. There is a simple applet showing the essence of the inductive proof of this result.
