Exploring Explicit and Recursive Rules in Arithmetic Sequences

The video tutorial explains how to describe sequences using both recursive and explicit rules. It begins with an introduction to the concepts, followed by a detailed explanation of the recursive rule, which relies on the previous term and a common difference. The explicit rule is then discussed, involving backtracking to find a starting value and applying a rate of change. The tutorial concludes with a practice example to reinforce understanding.
