What is the purpose of using page numbers in a document?

The primary purpose of using page numbers in a document is to provide reference points for readers. Page numbers help to organize the content, allowing readers to easily navigate through the document, locate specific information, or reference particular sections during discussions. By having distinct identifiers on each page, readers can refer to a particular page when quoting or discussing the document, ensuring clarity and precision in communication. This functionality is essential, especially in lengthy documents or reports where information is spread across multiple pages.

The other options, such as enhancing visual appeal, filling space, or making the document seem longer, do not capture the fundamental utility of page numbers, which is centered around usability and accessibility for the reader.
