Where to start on this challenge?

Hi, So you can see for yourself how this challenge is layed out, but I just can't seem to grasp it. I reviewed the video, but that didn't really help. Does anyone have a clue to get me going? Thank you!

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);

This is a little tricky. But I would suggest if using a for loop to initialize the var i at 2 so you start at two, then iterate through the loop adding 2 then consoling the i variable.

what we want is all even numbers how to go about doing that is to start a the count at 2, then iterate through the loop not by one but by 2. that way we get all the even numbers.
