I am not sure why the error is stating that I logged 13 numbers to the console and should have logged 12?

script.js 
var evenNumber = Math.floor(Math.random() * 24);
for ( var i = 0; i <= 24; i += 2) {
  console.log(evenNumber);

}

You increment 0 to 24 including 24 which is thirteen increments. If you were to start at 2 instead of 0 there would only be twelve. Also not sure what you are doing with the random number when you should be logging i.
