Answer: What Comes Next? #381

The answer is A: 78.

The rule

Add 13 each time.

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.

number = 0
for step in range(7):
    print(number)
    number = number + 13

When you run it, Python prints:

0
13
26
39
52
65
78
