## What is the sum of 1 to N?

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 1 to 1000?

The sum of first n natural numbers is given by the formula: n(n+1)/2. (In the 2nd equation, the terms to be summed are just written in the reverse order). So, the sum of numbers from 1 to 1000=1000*1001/2=500500.

## What is the sum of the first 125 natural numbers?

The number series 1, 2, 3, 4, . . . . , 124, 125. Therefore, 7875 is the sum of positive integers upto 125.

## What is the sum of first 50 odd numbers?

The number series 1, 3, 5, 7, 9, . . . . , 99. Therefore, 2500 is the sum of first 50 odd numbers.

## What is the sum of n terms?

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 1 to 99?

The number series 1, 2, 3, 4, . . . . , 98, 99. Therefore, 4950 is the sum of positive integers upto 99.

## How do you find the sum of 1 to 100?

The sum of the numbers 1-100 would be equal to the number of pairs (50) multiplied by the sum of each pair (101), or 50 x 101 = 5,050.

## What is the average of first 50 natural numbers?

Thus, 25.5 is an average of first 50 natural numbers or positive integers.

## What is the sum of first 50 even numbers?

The number series 2, 4, 6, 8, 10, 12, . . . . , 100. Therefore, 2550 is the sum of first 50 even numbers.

## What is the sum of odd numbers 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.
