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
Answer: 44
Hope this helps!
