7, 8, and 9

Explanation:

Integer 1: n
Integer 2: n+1
Integer 3: n+2

I added 1 or 2 to n because we don't know what number is after n, but we do know that they are consecutive.

Let's add these three integers and let them equal 24.

n + (n+1) + (n+2) = 24

Solve for n.

3n + 3 = 24

3n = 21

n = 7

We found that n is equal to 7. We can simply add 1 to find the next integer and add 2 to find the third integer. The three integers are 7, 8, and 9.
