Numerical Sequences and General Terms

This video tutorial introduces the concept of sequences, focusing on numerical sequences and their types, such as arithmetic and geometric progressions. It explains how to identify missing terms in sequences and discusses the Fibonacci sequence. The tutorial also covers sequence notation, including terms and positions, and demonstrates how to find the general term of a sequence. Finally, it provides practice problems to reinforce the concepts learned.
