Understanding and Finding Rules for Sequences with Arithmetic and Quadratic Progressions

The video tutorial explains sequences, focusing on arithmetic and quadratic sequences. It introduces the concept of terms and how to identify the rule governing a sequence. The tutorial covers arithmetic progression, emphasizing finding the common difference and the nth term. It also explores quadratic sequences, explaining the second layer difference and how to determine the nth term using algebraic methods.
