• Formula Representation: Express the general term (a_n) for each example as a formula, demonstrating how the multiplication rule translates into mathematical notation.

B. Recursively Defined Multiplying Series

• Explanation: Explain what a recursively defined multiplying series is, where each term is defined in relation to one or more preceding terms.
• Examples: Provide examples of recursive multiplying series. Include examples where the current term depends on only the previous term, and also examples where it depends on multiple previous terms.
• Importance of Initial Values: Emphasize the importance of specifying initial values for recursively defined series, as they are necessary to start the series.

C. Series Arising from Product Notation

• Explanation: Introduce the concept of product notation (Π) and how it can be used to represent multiplying series concisely.
