Question

anonymous · Answer

I think it's -18,-23,-28

anonymous · Answer

how did you figure that out?

anonymous · Answer

Take a look at the difference from the first to the second term.  And then take a look a the difference from the second to the third term.  If they are the same, then the difference from the third term to the fourth term should also be the same, as should that of the fourth to the fifth term.

anonymous · Answer

It would make more sense if that first 3 was negative.
