Answer 5

consecutive numbers are numbers one right after the other....for example : 1,2,3,4,5...these are consecutive.
So lets let one number be x, the other number is x + 1. and the last number is x + 2.
added together, they equal -27.
x + x + 1 + x + 2 = -27 -- combine like terms
3x + 3 = -27 -- subtract 3 from both sides
3x = - 27 - 3
3x = -30 -- divide by 3
x = - 10

x + 1 = -10 + 1 = -9
x + 2 = -10 + 2 = -8

numbers are -10,-9,-8 and that would be C....you are correct :)
