any even number can be divided by 2 until it reaches 1.
any odd number ends in 1,3,5,7,9. Any of those numbers multiplied by 3 and added to 1 ends in an even number. I don't get why this is hard?
6 wants to have a word with you.
It's hard because this is wrong.
18 is an even number. 18/2 is 9. 9 can no longer be divided by 2 and is not one.
What do you mean by that?
