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

var arrayOfInts = [1, 2, 3, 4, 5, 6]
// Add a 7th number using append method
arrayOfInts.append(7)
// Add an 8th number using concatenation and assign back to arrayOfInts
// NOTE: Use your variable, and assign the array back to the variable
arrayOfInts = arrayOfInts + [8] // OR This Way arrayOfInts += [8]
// Assign the 5th item in the array to constant value...NOTE: the array index starts at 0
let value = arrayOfInts[4]
//Remove the 6th item in the array and assign to discardedValue...NOTE: the array index starts at 0
let discardedValue = arrayOfInts.remove(at:5)

10,389 PointsHi,
The challenge is to retrieve the 5th item. Counting array starts with 0. So use 4 to retrieve the 5th value.
