You need to start the loop on the first value in the array which would be temperatures[0], so start by setting the variable i to that. Inside the loop you are logging out temperatures[0] which will continually log out "100" to the console. You need to instead log out every value in the array; since "i" is being incremented after every iteration of the loop you can use temperatures[i] inside of your console.log.

Yes, should look like this.

var temperatures = [100,90,99,80,70,65,30,10];

for (var i = 0; i < temperatures.length; i += 1){
     console.log(temperatures[i])
};

This will log 100 90 99 etc.
