Answer: What Comes Next? #292

The answer is A: red heart.

The finished pattern: red square, red heart, red circle, red heart, red square, red heart, red circle, red heart, red square, red heart.
The finished pattern.

The rule

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

When you run it, Python prints:

1 red square
2 red heart
3 red circle
4 red heart
5 red square
6 red heart
7 red circle
8 red heart
9 red square
10 red heart

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