Exploring Arithmetic Sequences

The video tutorial explains arithmetic sequences, highlighting their similarity to linear equations. It covers the concept of a common difference and how to derive the sequence equation. An example sequence is analyzed, and the process of finding specific terms, such as the 100th term, is demonstrated. The tutorial also shows how to determine if a given value is part of the sequence, emphasizing the need for whole number terms.

What is an arithmetic sequence?

• A sequence where each term is multiplied by a common ratio.

• A sequence where each term is a cube of the previous term.

• A sequence where each term is a square of the previous term.

• A sequence where each term is added or subtracted by a common difference.
