This is one of the most common causes of an unwanted blank page in the middle of a document too. If the empty page is the result of a manual page break, you can select the page break and press Delete to remove it.
Select them and then remove them by pressing the Delete key on your keyboard. If you have extra, blank, paragraphs at the end of your document you'll see empty paragraph marks (¶) on the blank page.
Turn on paragraph marks to see what's causing the blank page by clicking Show all nonprinting characters on the Standard toolbar. If that didn't work, then the cause of the blank page will take a little more investigation. On the Layout tab of the Ribbon, under Pages, click Remove On the View menu, click Publishing Layout. Your items aren't permanently deleted until you empty the Trash. Note: If you want to delete the entire document, rather than just one or more blank pages within the document, go to Finder, locate your file and drag it to Trash.
