Answer: What Comes Next? #375

The answer is B: 52.

The rule

Add 4, then add 10, then 4, then 10, and so on. The pattern of adding takes turns.

The pattern as Python code

Here is a tiny Python program that follows the same rule. Type it into IDLE and run it to print the whole pattern, including the answer.

adds = [4, 10]
number = 10
for step in range(7):
    print(number)
    number = number + adds[step % 2]

When you run it, Python prints:

10
14
24
28
38
42
52
