What is the number if it is 1 less than a square number and it is not divisible by 3 or 7 (You make a square number when you multiply something by itself, so 49 is square because it is 7 times 7)

Start with any number less than 20. If number is even, halve it and If number is odd, add one. Do they always end in 1?

Start with any number less than 20. If the number is even, halve it. If the number is odd, add one. Continue using the same rules writing each number one after the other. e.g. 17, 18, 9, 10, 5, 6, 3, 4, 2, 1.

Do they always end in 1? What is the longest list of numbers?
