Example Question #6 : Sequences And Series
Set R consists of multiples of 4. Which of the following sets are also included within set R?
Set W, containing multiples of 8.
Set X, containing multiples of 2.
Set Q, containing multiples of 7.
Set Y, containing multiples of 6.
Set Z, containing multiples of 1.
Set W, containing multiples of 8.
The easiest way to solve this problem is to write out the first few numbers of the sets.
Set R (multiples of 4):
Set W (multiples of 8):
Set X (multiples of 2):
Set Y (multiples of 6):
Set Z (multiples of 1):
Set Q (multiples of 7):
Given that Set W is the only set in which the entire set of numbers is reflected in Set R, it is the correct answer.
Example Question #3 : Sequences And Series
What number comes next in this sequence?
4 12 9 6 18 15 12 36 33 __
Determining sequences can take some trial and error, but generally aren't as intimidating as they may at first appear. For this sequence, you multiply the first term by 3, and then subtract 3 two times in a row. Then repeat. When you get to 33, you have only subtracted 3 once, so you have to do that one more time:
