Both of these extension methods are targeted at lists of data. One extends I innumerable and the other extends I list. Now to see these methods, you need to open up this file. Innumerable extensions. And then I'll scroll down to the bottom of this editor for the first method. It's this one here called index range. It's used to get a range of items from a list, or a subset of items.
