Answer: What Comes Next? #18

The answer is B: green hexagon.

The rule

The pattern repeats every 2 things: purple square, green hexagon. 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 square", "green hexagon"]
for position in range(8):
    print(position + 1, pattern[position % len(pattern)])

When you run it, Python prints:

1 purple square
2 green hexagon
3 purple square
4 green hexagon
5 purple square
6 green hexagon
7 purple square
8 green hexagon
