Hi Nick, I think you may have misread the question. If you look at the complete answer below you should be able to see what was being asked - hope this helps!

// Enter your code below
var arrayOfInts = [1,2,3,4,5,6]
arrayOfInts.append(7)
arrayOfInts = arrayOfInts + [8]
let value = arrayOfInts[4]
let discardedValue = arrayOfInts[5]
arrayOfInts.remove(at: 5)
