Answer: What Comes Next? #107

The answer is A: red triangle.

The finished pattern: red hexagon, red triangle, red triangle, red hexagon, red triangle, red triangle, red hexagon, red triangle.
The finished pattern.

The rule

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

When you run it, Python prints:

1 red hexagon
2 red triangle
3 red triangle
4 red hexagon
5 red triangle
6 red triangle
7 red hexagon
8 red triangle

Pixel says: Try changing a number in the code and run it again. Can you make the pattern go on for 20 steps? Meow!
