This is simple.
4) 21, 28, 33, 42, 43, 60, ?

  A. 45 B. 56 C.75 D.92
Ans:C

  5) 1, 3, 0, 6, 10, 9, ?

  A.13 B.14 C.15 D.17
Ans:D

Let's talk about 4 first.
It is a increasing series with alternated odd, even pattern.
Therefore, the next reasonable number would be 75.

For question 5, it appears to be randomly distributed positive numbers. pick any number from the answer would be reasonable. But A,B,and C are in sequence, so 17 is the choice.
