## What is the sum of first n odd numbers?

The first n odd natural numbers are given by 1,3,5,7,9…… (2n – 1) and this forms an AP. The sum of first n odd natural numbers is n2.

## What is the sum of first 10 natural numbers?

Hence, the sum of first n numbers is n(n+1)2 . Hence the sum of the first 10 terms, 1+2+3+… +10=55 .

## What is the sum of first 35 natural numbers?

630Answer. So sum of first 35 natural number is 630.

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

Clearly, it is an Arithmetic Progression whose first term = 1, last term = 100 and number of terms = 100. Therefore, the sum of first 100 natural numbers is 5050.

## Who found the sum of first 100 natural numbers?

GaussTherefore, the famous mathematician associated with finding the sum of the first 100 natural numbers is Gauss.

## 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.

## What is the sum of first 20 odd natural numbers?

Answer: The sum of the first 20 odd natural numbers is 400.

## What is the sum of first 30 natural numbers?

Sum of 1st 30 natural numbers?? The number series 1, 2, 3, 4, . . . . , 29, 30. Therefore, 465 is the sum of positive integers upto 30.

## What is the sum of all natural number from 1 to 100?

S100=n2[2a+(n−1)d]substituting the values. we getS100=1002[2×1+(100−1)×1]S100=50[2+99]S100=50×101S100=5050∴ The sum of first 100 natural numbers is 5050.
