+ 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 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 a sum of a series?

The sum of the terms of a sequence is called a series . If a sequence is arithmetic or geometric there are formulas to find the sum of the first n terms, denoted Sn , without actually adding all of the terms.

## 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 1 to 75?

2850 is a sum of number series from 1 to 75 by applying the values of input parameters in the formula.

## What is the sum of 1 to 40?

Interview Answer Any sum like this is easy. take the lowest and highest… 1 +40 = 41, then the next highest and the next lowest. 2 + 39 = 41.

## What is the sum of 1 to 365?

66795 is a sum of number series from 1 to 365 by applying the values of input parameters in the formula.

## 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 150?

The number series 1, 2, 3, 4, . . . . , 149, 150. Therefore, 11325 is the sum of positive integers upto 150.

## What is the sum of odd numbers from 1 to 40?

The number series 1, 3, 5, 7, 9, . . . . , 79. Therefore, 1600 is the sum of first 40 odd numbers.

## What is the sum of 1 to 25?

The number series 1, 2, 3, 4, . . . . , 24, 25. Therefore, 325 is the sum of positive integers upto 25.

## What is the sum of 1 through 30?

General Discussion. Sum of all the integers 1 through 30 inclusive = number of terms multiplied by (first term plus last term) divided by 2. So, s = 30×31/2 = 465. Factors of 465 = 1,3,5,15,31,93,155,465.

## What is the sum of 1 to 50 numbers?

1275 is a sum of number series from 1 to 50 by applying the values of input parameters in the formula.

## What is the sum of 1 to 200?

The number series 1, 2, 3, 4, . . . . , 199, 200. Therefore, 20100 is the sum of positive integers upto 200.

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

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) – [ (50 x 51)] = 5050 – 2550 = 2500.

## What is the total sum of 1 to 100?

What is the sum of the first 100 whole numbers? Gauss noticed that if he was to split the numbers into two groups (1 to 50 and 51 to 100), he could add them together vertically to get a sum of 101. Gauss realized then that his final total would be 50(101) = 5050.

## What is the sum of the number from 1 to 10?

The number series 1, 2, 3, 4, . . . . , 9, 10. Therefore, 55 is the sum of positive integers upto 10.

## What is the sum of 1 20?

210 is a sum of number series from 1 to 20 by applying the values of input parameters in the formula.

## What is the sum of 1 9?

By this formula then the sum of the integers from 1 to 9 is ((10)9)/2 = 45 = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9.

## What is the sum of 51 to 100?
