Code challenge problem

I am having trouble with this code challenge. I am supposed to combine all of the console.log() methods into a for loop.

"The code below logs all of the even numbers from 2 to 24 to the JavaScript console. However, there's a lot of redundant code here. Re-write this using a loop."

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);


var numbers = console.log(even);

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

for (var i=2; i<25; i=i+2)
{console.log(i)}

You've got some extraneous code that isn't necessary, re-watch the video on for loops. This entire thing can be solved within the for loop
