}

Remove the semicolon from the last part of the for loop parameters:

for (var i = 3; i<= 156; i+=1) {
  console.log(i);
}

Even though the other statements have a semicolon at the end of them, the last item should not have a semicolon in the conditions for your loop.

It's a bit confusing because every other statement you make in JavaScript ends in a semicolon, but this is a special syntax. Also, just so you know, you can use the auto incrementer instead of += for that loop -> i++.
