Answer: What Comes Next? #359

The answer is C: 55.

The rule

Take away 10 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 = 115
for step in range(7):
    print(number)
    number = number - 10

When you run it, Python prints:

115
105
95
85
75
65
55
