Understanding Sequences

This video tutorial introduces key sequence terminology, including arithmetic, triangular, Fibonacci, quadratic, and geometric sequences. It explains how to recognize and generate these sequences, highlighting concepts like common difference and common ratio. The video also provides practice problems and encourages viewers to explore further topics like the nth term in future videos.
