Firstly your loop would only print numbers 4 to 152. Secondly you are not increamenting the log variable at the end of the for loop with one.
```Javascript
for(var i=4; i<=156;i++){
console.log(i)
}
```

Hi. Let me try to explain.
This is the code you need to run: 
javascript
for (var i = 4; i < 157; i++) {
  console.log(i);
}

The for-loop is using a variable called i that is set to a number (this time its 4!).
The second argument in the four-loop is for how long it should loop around. If you want it to go from 4 until AND 156 you need to tell it to "go from 4 and stop when you have printed out 156". Therefor you need to do: "i less than 157". Because if it is the same value in this example, it won't print out 156.
The third argument is what you want to happen to the variable i. Here I am using "i++". Which is the same as:
javascript
i++
//or
i = i+1
//or 
i += 1

then you console.log(i), which has a new number every loop. But you need to have this inside your for-loop brackets, see the printed code on the top of this message.
Hope this helps, keep at it and happy coding!
