The problem asks for consecutive integers only. It does not ask for consecutive even integers, consecutive odd integers, or even integers spaced apart by 4 with -10 being the least in the range.

Therefore, possible series include:

-1, 0, 1
-2, -1, 0, 1, 2
-3, -2, -1, 0, 1, 2, 3

All of these series have an odd amount of integers b/c there will always be a counterbalancing negative integer for each positive integer to the right of 0.

The answer is E.

Thanks for the explanation. I got it wrong all this time, I thought consecutive integer can be apart by any amount (+1,+2,+3,etc) as long as it's consecutive. Got to look at the exact wording next time.

kudos +1 for you
