Answer: What Comes Next? #40

The answer is C: green circle.

The rule

The pattern repeats every 2 things: red circle, green circle. Then it starts again from the beginning.

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.

pattern = ["red circle", "green circle"]
for position in range(8):
    print(position + 1, pattern[position % len(pattern)])

When you run it, Python prints:

1 red circle
2 green circle
3 red circle
4 green circle
5 red circle
6 green circle
7 red circle
8 green circle
