    Answer:

    Σ(xᵢ-4)², i=1,2,3…

    Step-by-step explanation:

    Let a score be defined by x

    Each score will be xᵢ i.e. x₁, x₂, x₃, x₄… for the first four consecutive scores and so on.

    Subtracting 4 from each score = xᵢ-4

    Squaring the Resulting Value = (xᵢ-4)²

    The sum of the squared numbers = Σ(xᵢ-4)², i=1,2,3…

    Σ(xᵢ-4)² is the set of instruction expressed in summation notation.
