Answer:

-5,-4,-3

Explanation:

Let n be an integer.

The next integer would have to be n+1.

The integer before n would have to be n-1.

So the numbers in order are n-1, n , n+1

The sum of the first 2 equals 3 times the third:

n-1 + n = 3(n+1)

2n-1 = 3(n+1)

2n-1=3n+3

Subtract 2n on both sides

-1=n+3

Subract 3 on both sides

-4=n

If n=-4

then n-1=-5

and n+1=-3

So the three numbers are -5,-4,-3 .
