{"type":"rich","version":"1.0","title":"Geometric Series Formula Derivation","description":"Players arrange the steps of a geometric-series derivation in the correct order, such as writing the partial sum, multiplying by the common ratio, subtracting the equations, and solving for the sum. The learning goal is to understand why the finite geometric sum formula works, not just memorize it.
