Answer:
283
Step-by-step explanation:
Add the -5 to the 278 to get it, think the five is not negative but instead positive so you can add it.
282
Strictly speaking, between -5 and 278 means start at -4 and go to 277.
-4, -3, -2, -1, 0 ----> This accounts for 5 integers.
1, 2, 3, ..., 276, 277 ----> This accounts for 277 integers.
5 + 277 = 282
