Answer: What Comes Next? #281

The answer is D: 61.

The rule

Add 9 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 = 7
for step in range(7):
    print(number)
    number = number + 9

When you run it, Python prints:

7
16
25
34
43
52
61
