Question

What is the sum of the first three multiples of 7?

• A. 44
• B. 42
• C. 38
• D. 40

Answer 1

The correct option is B 42

To get the multiples of number 7, all we have to do is multiply 7 by 1, 2, 3 and so on.

That is,
$7\times 1=7,$
$7\times 2=14,$
$7\times 3=21,$
$7\times 4=28,$
and so on are the multiples of 7.

Hence, the first three multiples of 7 are 7, 14 and 21.

$\therefore$ The sum of the first three multiples of 7 is given by $7+14+21=42.$
