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.
