Answer:
If "n" is the first number, then the second number is "n + 1" and the third number is "n + 2"
That means n + (n + 1) + (n + 2) = -36
Combine like-terms to get: 3n + 3 = -36
Subtract 3 from both sides to get: 3n = -39
Divide both sides by 3 to get n = -13
So the first number is -13. The second number was "n + 1" so -13 + 1 = -12
The third number was "n + 2" so -13 + 2 = -11
So the 3 numbers are -13, -12, and -11
