The sum of two consecutive multiples of 2 is 18. Find the numbers

Solution:

Let the two consecutive multiples of 2 be x and (x + 2).

A/Q

x + (x + 2) = 18

2x + 2 = 18

2x = 18 - 2

x = 16/2

x = 8

Hence, x + 2 = 10

Thus, the two consecutive multiples of 2 are 8 and 10.

✦ Try This: The sum of two consecutive multiples of 3 is 21. Find the numbers.

Let the two consecutive multiples of 3 be x and (x + 3).

A/Q

x + (x + 3) = 21

2x + 3 = 21

2x = 21 - 3

x = 18/2

x = 9

Hence, x + 3 = 12

Thus, the two consecutive multiples of 3 are 9 and 12.
