Confused about this challenge

I thought I had the hang of the for loop and arrays, but I cannot figure out why I keep getting a syntax error for this code. I felt like I was right, but maybe I'm missing something?

script.js 
var temperatures = [100,90,99,80,70,65,30,10];
for (var i = 0; i < temperatures.length; i+= ){
  console.log(temperatures[i]);
  ]

It looks like there's two syntax errors here:

  • the function ends with a closing square bracket (]) but it should be a closing brace (})
  • "i+=" is not a complete expression, you probably meant "i+=1"
