  4. 2, 15

Answer: C

Explanation:

This is an alternating addition and subtraction series in which 3 is added to each number in the first pattern and 6 is subtracted from each number in the second pattern. Therefore, the next two numbers are 2 (8-6) and 16 (13+3).

Answer: A

Explanation:

In this series, the difference between the two consecutive numbers is 4, 9, 16, 25, and 37 (22 + 32 + 42 + 52 + 62). So, after 25 there should be 36, not 37, and after 56 there should be 92 (56+36) not 93.
