Follow a Rule to Find a Number in a Sequence

Number sequences sometimes use rules to generate the next number.

Here is a simple rule:

If the number is even, divide it by 2.

If the number is odd, subtract 1 from it.

Stop when you get to the number 1.

Look at this number worm, which shows this rule starting at the number 60.

That's quite a worm! Did you see how it follows the rule all the way from 60 to 1?

Let's have a go at some more number worms now.
