Answer: What Comes Next? #21

The answer is B: orange diamond.

The rule

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

When you run it, Python prints:

1 green diamond
2 orange diamond
3 green diamond
4 orange diamond
5 green diamond
6 orange diamond
7 green diamond
8 orange diamond
