This one is tricky. I think whoever wrote the problem messed it up, or you wrote it down incorrectly. I did the whole thing using y = -2, and I got the same answer you did. Then I thought further. If that answer didn't work, how else could the mode be -2? If x = -1, then 2 x -1 = -2, and makes the mode -2.

So, (-2 + 5 + -4 + -1 + y + -2)/6 = 3

-4 + y / 6 = 3

-4 + y = 18

y = 22

22 + -2 = 20

Which still isn't one of the possible choices. Sorry.
