The sum of three consecutive even number is 138. what is the smallest of the three

The sum of three consecutive even numbers is 138. What is smallest of the three numbers ?

Let the three consecutive even numbers be: n

n + 2 and n + 4

Therefore: n + n + 2 + n + 4 = 138

Combine like terms: 3n + 6 = 138

3n + 6 - 6 = 138 - 6

6 - 6 = 0

138 - 6 = 132

3n = 132

Divide each side by 3

3n/3 = 132/3

n = 44

Therefore the three consecutive even numbers are: 44, 46 and 48

Check: 44 + 46 = 90 + 48 = 138

44

Hope this helps!
