You are instructed to subtract 4 points from each score, square the resulting value, and find the sum of the squared numbers. How would this set of instructions be expressed in summation notation?

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.
