Which term refers to an ordered arrangement of related events or things?

The term that refers to an ordered arrangement of related events or things is "sequence." A sequence is a way of organizing information or events in a specific order, often to show how one event leads to another or to clarify the steps in a process. This term is commonly used in various contexts, such as storytelling, mathematics, and scientific processes, where understanding the order of events or components is essential for comprehension.
