A set of numbers has the property that for any number x in the set, x + 3 is also in the set. If 2 is in the set, which of the following must also be in the set? I. - 1 II. 5 III. 11

Explanation	Calculations	Help
$We apply the given property to x = 2 to find the next number in the set$	$2 + 3 = 5$
$We apply the property again to x = 5 to continue the sequence$	$5 + 3 = 8$
$We apply the property once more to x = 8 to reach 11$	$8 + 3 = 11$
$Statement I requires going backwards (subtracting 3), but the property only guarantees adding 3, not subtracting$	$2 - 3 = - 1$	Theory & Tactics Method Card LOGIC1-A Click to view full details
