from experience, pages are ALWAYS numbered from 0 to N-1

a pages page number can and will change whenever it's position in the number
sequence 0 to N-1 changes.

It's not so hard a concept, and is the only way that makes any sense when you
think about it from a development / implementation point of view.

In your specific example, starting with 4 pages, numbered from 1 thru 3, when
one is removed, the remaining 3 pages are numbered 0 thru 2. If it was the last
page that was removed, then there is no change to the number of any page. If it
was a page other than the last, then all pages after the removed page will
shuffle down.

All the best,
