Answer: What Comes Next? #112

The answer is A: yellow triangle.

The rule

The pattern repeats every 3 things: purple heart, yellow triangle, yellow 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 = ["purple heart", "yellow triangle", "yellow triangle"]
for position in range(8):
    print(position + 1, pattern[position % len(pattern)])

When you run it, Python prints:

1 purple heart
2 yellow triangle
3 yellow triangle
4 purple heart
5 yellow triangle
6 yellow triangle
7 purple heart
8 yellow triangle
