Answer: What Comes Next? #443

The answer is C: 189.

The rule

Add 23 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 = 51
for step in range(7):
    print(number)
    number = number + 23

When you run it, Python prints:

51
74
97
120
143
166
189
