Answer:
-135, -134, -133
Explanation:
Hi there!
Let x be equal to the first integer in the set of three consecutive integers.
Let x+1 and x+2 be the consecutive integers.
We're given that they have a sum of -402.
We can construct an equation:

Combine like terms:

Therefore the first integer is -135.
The next two consecutive integers after -135 is -134 and -133.
Therefore, the three consecutive integers are -135, -134 and -133.
I hope this helps!
