Answer: What Comes Next? #149

The answer is B: 13 dots.

The rule

Each picture has 2 more dots than the one before.

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.

dots = 3
for step in range(6):
    print(dots)
    dots = dots + 2

When you run it, Python prints:

3
5
7
9
11
13
