I’d like to call a moratorium on this word.
Recall the formula for the sum of a finite geometric sequence where is
Unless what you’re asking the reader to recall is in the same book as you’re writing, don’t use this word. Any prerequisite texts / courses your reader may have had might have used different terminology, or the class just skipped that section, or maybe they forgot so completely that there’s nothing to recall. Or perhaps they remember a particular formula exists, but based on the wording of “recall” feel silly that they hadn’t memorized it.
