consecutive integers are integers that come one after the other. Ex: 1 2 3 are consecutive as are 7 8 9... etc 
for this problem, since we do not know the value of the integer we shall call it x.
So we have:
x + (x+1) + (x+2)=-78
combine like terms:
x+x+1+x+2=-78
3x+3=-78
3x=-81
x=-27
 
so the answer is -27, -26, and -25
 
 
 
 
 
Hi Haley ... with 3 consecutive integers, the middle no. is the average ... divide by 3 ...
 
-78 cut in 3rds is -26 -- the middle number ... -25, -26, -27 works ... Best wishes :)
