## What is the difference between the odd number and the sum of the even numbers?

The sum of an even number of odd numbers is even, while the sum of an odd number of odd numbers is odd. For instance, the sum of the four odd numbers 9, 13, 21 and 17 is 60, while the sum of five odd numbers 7, 15, 19, 23 and 29 is 93.

What is the sum of odd numbers between 1 to 10?

### What is the sum of even numbers from 1 to 10?

Therefore, the first 10 even natural numbers will be 2, 4, 6, 8, 10, 12, 14, 16, 18 and 20. Hence, the required sum of the first 10 even natural numbers is 110.

What is the difference between even and odd numbers?

An even number is a number that can be divided into two equal groups. An odd number is a number that cannot be divided into two equal groups. Even numbers end in 2, 4, 6, 8 and 0 regardless of how many digits they have (we know the number 5,917,624 is even because it ends in a 4!). Odd numbers end in 1, 3, 5, 7, 9.

#### What is the difference between the sum of even numbers and the sum of odd numbers between 10 and 20?

From the above solution, the difference of the sum of even numbers and sum of odd numbers between 10 and 20 is 15. So, the correct answer is “Option C”.

## What is the sum of all even numbers from 15 to 100?

Since the difference between each corresponding term in both EVE and ODD is 1, the sum of the differences is 1 * number of terms = 1 * 43 = 43. This will also be the difference of the sums of the of the two series. Therefore, the difference between the sum of all even numbers and of all odd numbers from 15 to 100 is 43.

How do you find the sum of even and odd numbers?

Also, find sum of odd numbers here. Basically, the formula to find the sum of even numbers is n (n+1), where n is the natural number. We can find this formula using the formula of the sum of natural numbers, such as: S = 1 + 2+3+4+5+6+7…+n. S= n (n+1)/2.
