I can't remove the sixth term

the task is asking for me to remove the sixth term of an array. the sixth term is the number 6 and the array goes [1,2,3,4,5,6,7,8] so to remove the sixth term i typed arrayOfInts(at: 5) and it works on xcode it does remove the number 6. but here its giving me a hint saying make sure i remove the sixth term from the index 5.

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

HI Julio,

You did all the hard stuff right!

You didn't properly set your constant discardedValue to the 5th removed index. It should have been like this:

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