Your code: 

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

You set the i = 2. So if you start adding 2 each time from that number up to 24 you will get 11. But if you had set the i = 0, it will work because now it will call 12 times. So you could equally do this:

for (var i = 0; i < 24; i += 2) {
console.log(i)
}

thats correct but the questionnaire would then error and say, your not adding up in even numbers, as i tried that exact code, your spot on though mate thanks for your reply
