Question

the sum of three consecutive positive even integer is 18 find the numbers

Answer 1

Given: Sum of three consecutive even integers is 18.

To find: The numbers.

Answer:

Let one of the numbers be x.

Difference between two even numbers = 2 (4 - 2 = 2, 6 - 4 = 2, 80 - 78 = 2).

Therefore the other number will be x + 2. And the third number will be x + 4 as x + 2 + 2 = x + 4.

x + x + 2 + x + 4 = 18

3x + 6 = 18

3x = 18 - 6

3x = 12

x = 12/3

x = 4

Therefore the numbers are x = 4, x + 2 = 4 + 2 = 6 and x + 4 = 4 + 4 = 8.

Hope it helps :)
