The challenge wants you to use DRY programming (Don't Repeat Yourself) to print the even numbers between 2 and 24. You can do this by creating a for loop like so:

for(var i = 2; i <= 24; i += 2){
  console.log(i);
}

Ah I see so you just add two instead of 1 to the counter every time. I'm always looking for some mega complicated solution to these when I first see them.

Thanks

Correct. It is really easy to over think these things. :)
