Answer:
the three even integers are -28, -26 and -24.
Step-by-step explanation:
Represent the three numbers as follows:
n
n+2
n+4
Their sum is n + n+2 + n+4 = -78.
Combining the n terms, we get:
3n + 6 = -78, or
3n = -84
Then n = -84/3, or n = -28.
Then the three even integers are -28, -26 and -24.
