"Cause and Effect" is the 16th episode and the season finale of the sixth season and series finale of the American television series Numb3rs. In the episode, Federal Bureau of Investigation (FBI) agents and mathematicians attempt to find one agent's gun before it is used in a violent crime. When series creators/executive producers Cheryl Heuton and Nicolas Falacci learned that the number of episodes airing during the season was reduced, they felt that they needed to finish storylines in case the series was cancelled. To do so, they wrote an open-ended story to serve as either a season finale or a series finale.

Originally set to air in May, "Cause and Effect" first aired in the United States on March 12, 2010. Critics mostly focused on the potential cancellation of the series, but two reviewers gave the episode reviews. "Cause and Effect" became Numb3rs series finale after CBS's cancellation of the series on May 19, 2010.

Drs. Charlie Eppes (David Krumholtz) and Amita Ramanujan (Navi Rawat) are married at CalSci. Charlie's father Alan Eppes (Judd Hirsch), Charlie's older brother FBI Special Agent Don Eppes (Rob Morrow), and friends FBI Special Agents David Sinclair (Alimi Ballard), Colby Granger (Dylan Bruno), Nikki Betancourt (Sophina Brown), and Assistant United States Attorney Robin Brooks (Michelle Nolden) attend the ceremony. Charlie and Amita's friend and colleague Dr. Larry Fleinhardt (Peter MacNicol) officiates. After receiving a call from FBI Special Agent Liz Warner (Aya Sumika), Don and David leave the reception to arrest Ted Dacosta (Luke Rosen), a man wanted on fraud charges. During the arrest, a man who has just learned that Decosta had swindled him tackles Don and David. The tackle knocks Don's gun away from him. Someone picks the gun up and walks away from the scene. A member of the Los Angeles Police Department (LAPD) questions Don about the incident, and Don completes the required paperwork. Nikki contacts her former colleagues at the LAPD for assistance.
