Exploring Arithmetic Sequences Fundamentals

The video tutorial introduces sequences, focusing on arithmetic sequences where the difference between consecutive terms is constant. It explains the concept of terms in a sequence and demonstrates how to derive and apply the formula for arithmetic sequences using examples. The tutorial also covers the concept of infinite sequences and provides a step-by-step breakdown of calculating terms using the common difference.
