The page needs to be initialized to the items : var page=items; Then u need to skip(20), which means 2 pages gone, and Take(10), which makes the 3rd page...

just keep in mind the formula and whatever the numbers will be, you'll be able to solve it: Skip((page - 1)*pageSize).Take(pageSize) example: Skip((3 - 1)*10).Take(10) number of pages : 3 pageSize refers to the items displayed by page: 10
