If you don't get the question, that's exactly what I want to know.
Imagine we have a ordered list of fruits.
["Apple", "Banana", "Peach", "Orange"]
I want the 3rd fruit in that list. But you don't know which one I want. How one asks which member in the sequence I want.
What nth fruit do you want?
Now, I know that this is wrong. I'm looking for the right expression to ask this. I hope my question is now clear.
