Answer: What Comes Next? #184

The answer is A: green triangle.

The rule

The pattern repeats every 3 things: blue triangle, green triangle, red triangle. 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 = ["blue triangle", "green triangle", "red triangle"]
for position in range(8):
    print(position + 1, pattern[position % len(pattern)])

When you run it, Python prints:

1 blue triangle
2 green triangle
3 red triangle
4 blue triangle
5 green triangle
6 red triangle
7 blue triangle
8 green triangle
