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.
