Given three ints, one of them small, one medium, and one large, return true if the three values are evenly spaced: So the difference between small and medium is the same as the difference between medium and large. For example, the values 2, 4, 6 and 6, 4, 2, and 4, 6, 2 are all evenly spaced, but 4, 6, 3 are not.
