Answer: What Comes Next? #412

The answer is B: 768.

The rule

Double the number each time (multiply by 2). Doubling makes numbers grow really fast!

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 = 12
for step in range(7):
    print(number)
    number = number * 2

When you run it, Python prints:

12
24
48
96
192
384
768
