Finding Terms in Arithmetic Sequences

The video tutorial explains how to find missing terms in an arithmetic sequence. It begins with an example sequence and identifies the given values. The tutorial then demonstrates how to calculate the common difference and use it to find the missing terms. The process is broken down into clear steps, making it easy to follow. The video concludes with a summary of the steps and encourages viewers to apply the method to similar problems.
