Set M contains number that satisfy the condition that, if integer x is in the set then x + 4 will also be in the set M. If -4 is one value in the set, which of the following values must also be present in the set M? I) -8 II) 4 III) 8	Choose the correct choice from the following: A) I only B) II only C) I and II only D) II and III only E) I, II and III
Since -4 is in the set, then the set must also include 0, 4, 8, 12, etc...   Depending on whether -4 is the starting element in the set or not, we can have -8...or not.   The answer is II and III only.
