What term describes the following? an equation that recursively defines a sequence based on its previous terms.
Difficulty: Hard
About this MCQ
This Hard Discrete Mathematics MCQ checks one syllabus fact.
The question is: “What term describes the following? an equation that recursively defines a sequence based on its previous terms.”
The accepted answer is D. Recurrence relation. Recurrence relation is the fact required by “What term describes the following? an equation that recursively defines a sequence based on its previous terms.” (option D). Option A (“Modular arithmetic”) does not match the stem; it is a near-miss used to catch incomplete recall of Recurrence relation. Option B (“Graph theory”) does not match the stem; it is a near-miss used to catch incomplete recall of Recurrence relation. Remaining alternatives (Permutation) fall outside the same rule and should be eliminated once Recurrence relation is identified. Discrete Mathematics questions of this type reward precise definitions rather than approximate associations. Discrete Mathematics recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
