Special Interest: Hailstone Sequence

This problem introduces students to one of the world’s unsolved problems in mathematics, which is, in itself very cool.

It involves a sequence of numbers called a Hailstone sequence. It is called this because the numbers go up and down again.

For example: 20 – 10 – 5 – 16 – 8 – 4 – 2 – 1

Hailstone Sequences follow these rules:



If a number is even, divide it by 2 If a number is odd, multiply it by 3 and add 1

Can you solve it??
