How to solve a set with '...'s on both sides such as, {...,-1,0,1,...} and covert into set notation?

The set shown is an infinite set, the ellipses mean "and so on" down to - infinity and up to plus infinity.

What you have there is the set of all integers, positive and negative. In set builder notatoin, ths would be

{x | x e Z}, where Z is the set of all integers.
