Creating a for loop

Is this how I create a for loop?

script.js
for ( let counter = 5; counter <= 100; counter += 45 ) {
  console.log(counter);
}

Hi Frank. Yes that is the proper format for a for loop. But I’m confused why are you counting by 45? You want all number 5 to 100. So you start at 5 and count while counter <= 100. that’s all correct. But you want to count by 1. not 45. counting by 45 will give you the output: 5 50 95.

You want to end your for loop with: counter += 1

Not counter += 45
