I got: 14,15 and 16

Explanation:

Call your integers:
n
n+1
n+2
we get
n+(n+1)+(n+2)=45
3n=45-3
n=42/3=14

So our integers are:

14,15 and 16

13,15,17

Explanation:

There are two methods:
1. Guess random numbers and check
2. Use an equation.

To use an equation, we know that 15*3 is 45, so we can automatically adjust that the middle number is 15.

Then, since it's consecutive, we can just add the right number by 2 then subtract the left number by 2 to get 13, 15, and 17.

This actually works for any other similar situation, for example:

Find 3 consecutive integers that add up to 90.

90/3=30.

30-2=28, 30+2=32.

28+30+32=90.

Note: However, this does depend on the situation at hand, since it can ask for consecutive even or odd integers.
