Am I putting this in right?

The question is asking me to remove index 5, which is 15, yet it is still telling me that I am wrong?

// Enter your code below
var arrayOfInts = [1,9,8,90,76,15]


arrayOfInts = arrayOfInts + [98]

arrayOfInts [4] = 76

let value = 76

arrayOfInts.remove(at: 5)

let discardedValue = 15

You are actually pretty close. instead of assigning 15 to the constant discardedValue, you should assign the removed value directly to the constant. Your code will look like this:

let discardedValue = arrayOfInts.remove(at: /*put your index number here*/)
