## What is the sum of n numbers?

Sum of N Terms Formula 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. For example: 1, 4, 9, 16, 25, 36, 49 ……….

## What is the sum of odd numbers?

The total of any set of sequential odd numbers beginning with 1 is always equal to the square of the number of digits, added together. If 1,3,5,7,9,11,…, (2n-1) are the odd numbers, then; Sum of first odd number = 1. Sum of first two odd numbers = 1 + 3 = 4 (4 = 2 x 2).

## What is the sum of the odd numbers from 1 to 100?

So we can do the following: Sum of odd consecutive integers from 1 to 100 = (Sum of all consecutive integers from 1 to 100) – (Sum of even consecutive integers from 1 to 100). Sum of odds = (100 x 101/2) – [2 x (50 x 51/2)] = 5050 – 2550 = 2500.

## What is the sum of the first 100 numbers?

I love the story of Carl Friedrich Gauss—who, as an elementary student in the late 1700s, amazed his teacher with how quickly he found the sum of the integers from 1 to 100 to be 5,050.
