You are looking to use subscript to read a value from an array.

Task 3 of the challenge asked you to take the 5th item in the array and assign it to a constant named value. It would look like this.

let value = arrayOfInts[4]

As mentioned in the challenge the array starts numbering its items at index number 0. So the 5th number in the array would be at index 4.
