Question

The sum of three consecutive even numbers is 168.
What is the smallest of the three numbers?

Answer 1

55

Explanation:

Answer 2

54

Explanation:

Let's take the unknown variable as "x".

Since they are consecutive even numbers, we add 2 for each one.

=> x + x + 2 + x + 4 = 168

=> 3x + 6 = 168

=> 3x + 6 - 6 = 168 - 6

=> 3x = 162

=> 3x/3 = 162/3

=> x = 54

So, the smallest number from those 3 consecutive numbers is 54.
