  2. Observe the configuration of points, for different values of \(n\).
  3. Find the sum value.
  4. Some apps have suggestions to help find the sum value. To see them, move from left to right the corresponding point. When there are several tips, they can been seen only by the presented order.
  5. To check the solution, move from left to right the corresponding point.

Remark: After dragging a point from a slider, you may find yourself not able to deselect it. If such a situation occurs (which should be sporadic), just double click on the selected point.
