Which term correctly identifies a phrase that refers to a sequential relationship?

The term that identifies a phrase indicating a sequential relationship is "Finally." This word is commonly used to denote the last item in a series or the conclusion of a sequence of events. In contexts where time or order is being emphasized, "finally" suggests that there have been previous steps or events leading up to this point, making it inherently related to the concept of sequence.

In contrast, terms like "all year" connote duration without specifically indicating a sequence, while "frequently" implies regular occurrence but does not establish an order. The term "before" indicates a relationship of time but is not specifically sequential in the way that "finally" conveys a clear progression towards the last event or conclusion in a series. Thus, "finally" is the most appropriate term for describing a sequential relationship.
