Answer: What Comes Next? #435

The answer is C: 161.

The rule

Add 20 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 = 41
for step in range(7):
    print(number)
    number = number + 20

When you run it, Python prints:

41
61
81
101
121
141
161
