1. You are listing two authors:
* Example: Smith, J., and Jones, A. (2023).
2. You are listing three or more authors in a reference list:
* Example: Brown, K., Green, R., and White, T. (2022).
3. You are listing multiple authors in the text of your paper (in parentheses):

However, you use an ampersand (&) instead of "and" in some cases:
* In parenthetical citations with more than two authors:

* In reference lists when using the APA style guide:
* Example: Brown, K., Green, R., & White, T. (2022).
It's important to follow the specific style guide's rules for formatting citations. Check your style guide (e.g., APA, MLA, Chicago) for the most accurate and up-to-date information.
