APA Style (7th ed.)
Use Arabic numerals (e.g., 1, 2, 3) throughout the document, and continue the page numbers sequentially to the end of the report, including all appendices (APA, 2020, p. 30). Page numbers should be right-aligned in the header (American Psychological Association, 2020, p. 44); see the page numbers in the Annotated Student Sample Paper for examples of this formatting. The APA Style manual asks that both journal article manuscripts and student papers display a page number on the title page, but students should follow the guidelines of their course instructor to determine the appropriate title page format. If you are uncertain whether to provide a page number on the title page of your work, please check with your instructor or advisor.
