Set up an equation. Your equation should look like this: n+(n+3)+(n+6)=36

n is the smallest number, therefore n+6 is the largest.

To simplify your equation, it looks like: 3n+9=36

Subtract 9 from both sides.

3n+9-9=36-9

3n=27

Now divide both sides by 3.

3n/3=27/3

n=9

The smallest number is 9.

To find the largest number, add 6 to n.

9 + 6 = 15

The greatest number is 15.

The middle number is 9 + 3 = 12. The middle number is 12.

We can go back and check our work.

9 + 12 + 15 = 36

9, 12, and 15 are consecutive multiples of 3.

Therefore, your answer is *15*.
