Understanding Sequences: Arithmetic, Geometric, or Neither

The video tutorial explains how to determine if a sequence is arithmetic, geometric, or neither. It covers the concepts of common difference and common ratio, providing methods to identify these in sequences. The tutorial includes examples of arithmetic sequences, where a constant is added to each term, and geometric sequences, where each term is multiplied by a constant. It also discusses how to identify sequences that are neither arithmetic nor geometric.

What is the defining characteristic of an arithmetic sequence?

• A common difference between terms

• A common ratio between terms

• Terms that are squares of integers

• Terms that are cubes of integers

What indicates that a sequence is neither arithmetic nor geometric?

• It has neither a common difference nor a common ratio

• It has a common ratio but no common difference
