Nth Term Murder Mystery | Mario-Themed KS3 & Functional Skills Maths Activity | Sequences Revision

This Mario-themed Nth Term Murder Mystery is a high-engagement sequences activity perfect for KS3 Maths, GCSE Foundation, and Functional Skills Level 1–2 learners. Students must use nth-term formulas to check calculations made by characters such as Mario, Luigi, Yoshi and Donkey Kong, identify errors, and use the clues to work out* who committed the crime*, where it happened and on which day.

The task requires learners to substitute into nth-term expressions, calculate missing terms, spot incorrect answers and apply reasoning across three clue sets—Who? Where? When? This makes it ideal for retrieval practice, consolidation or a fun problem-solving lesson.

Great as a main activity, revision session, group challenge or end-of-term treat.
