The Newspapers Puzzle

Do you like to read newspapers?
As a matter of fact I do, but I like crosswords the most!
Anyway, here is one interesting puzzle I recently found.

A newspaper called “The Apple” should be exactly 100 pages. I saw that page 51 and page 90 are missing. Can you determine which other pages will be missing?

Now something really harder! A newspaper called “Newton” should be exactly 9 999 999 pages, but page 999 and page 878787 are missing. Can you determine the missing pages?
