Answer: What Comes Next? #25

The answer is D: blue triangle.

The rule

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

When you run it, Python prints:

1 blue triangle
2 blue triangle
3 orange triangle
4 blue triangle
5 blue triangle
6 orange triangle
7 blue triangle
8 blue triangle
