Answer: What Comes Next? #284

The answer is A: green heart.

The finished pattern: purple square, green heart, blue circle, green heart, purple square, green heart, blue circle, green heart, purple square, green heart.
The finished pattern.

The rule

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

When you run it, Python prints:

1 purple square
2 green heart
3 blue circle
4 green heart
5 purple square
6 green heart
7 blue circle
8 green heart
9 purple square
10 green 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!
