E. None of the above

Answer: B. 22

This is an alternating number subtraction series.
First, 2 is subtracted, then 4, then 2, and so on.
Rule = (first number - 2) (second number - 4) (third number - 2) (fourth number - 4)......
Now The series is 36, 34, 30, 28, 24...
(36 - 2 = 34), (34 - 4 = 30), (30 - 2 = 28), (28 - 4 = 24), (24 - 2 = 22)...
So the answer is b = 22.
