Don't know where to begin

Really unsure how to solve this challenge, would be great to get a few hints if anyone has done this

script.js 
console.log(2);
console.log(4);
console.log(6);
console.log(8);
console.log(10);
console.log(12);
console.log(14);
console.log(16);
console.log(18);
console.log(20);
console.log(22);
console.log(24);

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. :)
