Which of the following is NOT a signal word that indicates sequential order?

The choice that represents a term not indicating sequential order is "whenever." This word refers to a time frame or a conditional event rather than a specific order of occurrences. It implies an action that takes place at any time and does not explicitly signify a sequence of events.

In contrast, words like "first," "next," and "finally" explicitly indicate the progression of steps or events in a chronological sequence. "First" marks the beginning of a sequence, "next" indicates the subsequent step, and "finally" signifies the conclusion of that sequence. Understanding these distinctions helps in recognizing how certain words convey time relationships and sequences in writing.
