The keyword "var" should only be used once. The variable name is "i".

Then, the original code logged "all of the even numbers from 2 to 24", but this code logs the odd numbers from 1 to 23 instead (try starting with an even number).

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

You didn't log out the even numbers from 2 to 24. what am i missing ?

You forgot to pass the variable "i" as the argument :point_right: console.log(i);
