Question

The sum of three consecutive even numbers is 48. What is the smallest number

Answer 1

We have the follwing:

$a+(a+1)+(a+2)=48$

So, we solve for a and we will find the smallest number:

$\Rightarrow3a+3=48\Rightarrow3a=45\Rightarrow a=15$

So:

15 + 16 + 17 = 48.

The smallest number is 15.
