It'll work if you have [1, 2, 3, 4, 5], but it will fail if you have [1, 2, 3, 4, 5, 6]. That's why the last one of course, is "the hardest."
There are a few way to do this. You could check the length of the iterable using an if statement and use the appropriate code on whether it's even or not. But, I think the DRYest way is to get all the even numbers from the iterable first, and then reverse the order.
If you need to, you can have a look at this post, where Jeff does provide the answer. Give it a shot first with the above in mind, then if you are still stuck, you can look at Jeff's answer.
Keep Coding! :)
