Question

Find the sum of first 10 multiples of 4

Answer 1

Here is the answer for your question.

Answer 2

Given:

First 10 multiples of 4

To find:

The sum of the given multiples

Solution:

The required sum is 220.

We can obtain the sum's value by adding the given multiples of 4.

We can have the multiples by multiplying 4 with 1, 2, 3, and so on till 10.

The multiples given are as follows-

4, 8, 12, 16, 20, 24, 28, 32, 36, 40.

This forms a progression with first term=4, last term=40.

So, the required sum=N/2(A+L), where N is the total multiples, A is the first term and L is the last term.

Using the values,

Sum=10/2(4+40)

=5×44

=220

Therefore, the required sum is 220.
