Answer: What Comes Next? #297

The answer is D: red square.

The rule

The pattern repeats every 4 things: red triangle, red square, red triangle, red star. 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 triangle", "red square", "red triangle", "red star"]
for position in range(10):
    print(position + 1, pattern[position % len(pattern)])

When you run it, Python prints:

1 red triangle
2 red square
3 red triangle
4 red star
5 red triangle
6 red square
7 red triangle
8 red star
9 red triangle
10 red square
