The main issue is that you are starting num with a value of 0. The first time you go through the loop it will increment num by 1 and then log it’s new value, 1, to the console.

You can simplify this by foregoing the num variable and logging the for loop index to console instead. For example:

for (i=4;i<=156;i+=1) { 
    console.log(i); 
}
