"I never see what has been done; I only see what remains to be done."
- Marie Curie

In each series, look for the degree and direction of change between the numbers. In other words, do the numbers increase or decrease, and by how much

3.

Look at this series: 36, 34, 30, 28, 24, ... What number should come next?

 [A]. 20 [B]. 22 [C]. 23 [D]. 26

Explanation:

This is an alternating number subtraction series. First, 2 is subtracted, then 4, then 2, and so on.

So the next difference is 2 (4,2,4,2,4, next number 24-2=22
