This Explicit Formulas: Tiles for Writing nth Term in a Sequence interactive also includes:
Build an explicit formula using tiles. Pupils develop a tile representation of a term within a sequence given figures of previous terms. Using the diagrams, learners develop the explicit formula by recognizing the common difference and the initial value. To complete the simulation, scholars use the formula to find the value of a specific term.
