Set M contains number that satisfy the condition that, if integer x is in the set then x + 6 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) -10 II) 2 III) 8  Choose the correct choice from the following answers:	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 2, 8, 14, 20, etc...   Depending on whether -4 is the starting element in the set or not, we can have -10...or not.   The answer is II and III only.
