Answer: What Comes Next? #399

The answer is A: 115.

The finished pattern: 31, 45, 59, 73, 87, 101, 115.
The finished pattern.

The rule

Add 14 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 = 31
for step in range(7):
    print(number)
    number = number + 14

When you run it, Python prints:

31
45
59
73
87
101
115

Pixel says: Try changing a number in the code and run it again. Can you make the pattern go on for 20 steps? Meow!
