Which term describes a sequence where each term follows a certain pattern or rule?

The term that accurately describes a sequence where each term follows a certain pattern or rule is the concept of a sequence itself, which can be referred to as a term. A sequence is a set of numbers or objects arranged in a specific order according to a defined rule or pattern. This ensures that each term in the sequence can be derived from its preceding terms based on a specific formula or relationship.

In the context of mathematics, various types of sequences exist, such as arithmetic sequences and geometric sequences, both of which have distinct patterns. However, the term "sequence" encompasses all types of ordered collections where terms follow established rules. Hence, the answer highlights the foundational concept of sequences in mathematics.
