Reading from array and creating new constant. Need help with 3rd part of this question.

I understand about adding arrays and reading from them, However cannot understand why I am not passing this stage of the challenge.

array.swift 
// Enter your code below
var arrayOfInts = [0,1,2,3,4,5]
arrayOfInts.append (6)
arrayOfInts += [7]

arrayOfInts[5]

let value = arrayOfInts[5]

Hi Connor,

Array indexes start at 0, not 1, so the value you're currently passing would return the sixth element, not the fifth. You know what to do! ;)

Array elements starts at 0, not 1. This means that 0 is the 1st element, so to get to the 5th element, you actually ask for the element at position 4 of the array.
