The diary sheet

John found a loose sheet of a newspaper. The sum of the 4 page numbers on the sheet is equal to 50.

How many pages did the newspaper to which the sheet belonged?


The four pages of a sheet of the same newspaper always add up to the same, and it is 2X + 2 with X being the total number of pages in the newspaper. In this specific case the newspaper had 24 pages or six sheets.
