Solved Examples

Example 1: What is the sum of first 8 multiples of 3?

The first 8 multiples of 3 are

3, 6, 9, 12, 15, 18, 21, 24

So, sum of their is

3 + 6 + 9 + 12 + 15 + 18 + 21 + 24 = 108

the sum of first 8 multiples of 3Thus, the sum of first 8 multiples of 3 is 108. The first number is 3, the last number is 24. The average of first 8 multiples of 3 is 13.5.

Example 2: Find the sum of first 10 multiples of 6.

The first 10 multiples of 6 are

6, 12, 18, 24, 30, 36, 42, 48, 54, 60

So, sum of their is

6 + 12 + 18 + 24 + 30 + 36 + 42 + 48 + 54 + 60 = 330

Use the sum of first N multiples calculator to calculate the sum of first 10 multiples of 6.

the sum of first 10 multiples of 6Thus, the sum of first 10 multiples of 6 is 330. The first number is 6, the last number is 60. The average of first 10 multiples of 6 is 33.
