Perpendicular lines to the x-axis are drawn through points A₁, A₂, A₃, ... respectively, intersecting the graph of the inverse proportion function y = (4/x) (x > 0) at points P₁, P₂, P₃, .... Connect OP₁, OP₂, OP₃, ..., which intersect P₁A₂, P₂A₃, P₃A₄, ... respectively at points Q₁, Q₂, Q₃, .... The triangle △OP₁A₁, quadrilateral A₁Q₁P₂A₂, quadrilateral A₂Q₂P₃A₃, quadrilateral A₃Q₃P₄A₄, ... are formed, and their areas are denoted by S₁, S₂, S₃, S₄, ..., and so on. **Chart/Diagram Description:** - Type: A 2D coordinate plane diagram showing the positive x-axis and y-axis. - Coordinate Axes: The x-axis is labeled 'x' and the y-axis is labeled 'y'. The origin is labeled 'O'. - Curve: A smooth curve in the first quadrant, which is part of the graph of an inverse proportion function. - Points on x-axis: Points O, A₁, A₂, A₃, A₄, A₅ are marked on the positive x-axis. Markings indicate that the lengths of segments OA₁, A₁A₂, A₂A₃, A₃A₄, A₄A₅ are equal. - Vertical Lines: Vertical line segments P₁A₁, P₂A₂, P₃A₃, P₄A₄, P₅A₅ are drawn from points P₁, P₂, P₃, P₄, P₅ on the curve to the x-axis at A₁, A₂, A₃, A₄, A₅ respectively. Right angle symbols are shown at A₁, A₂, A₃, A₄, A₅, indicating these are perpendicular to the x-axis. - Points on the curve: P₁, P₂, P₃, P₄, P₅ are points on the curve. P₁ is vertically above A₁, P₂ is vertically above A₂, etc. - Lines from Origin: Line segments OP₁, OP₂, OP₃, OP₄ are drawn from the origin to the points P₁, P₂, P₃, P₄ on the curve. - Intersection Points: Q₁ is the intersection of OP₂ and P₁A₂. Q₂ is the intersection of OP₃ and P₂A₃. Q₃ is the intersection of OP₄ and P₃A₄. Q₄ is the intersection of OP₅ and P₄A₅. These points are located on the vertical segments P₁A₂, P₂A₃, P₃A₄, P₄A₅ respectively. - Geometric Figures: Several regions are outlined: △OP₁A₁, quadrilateral A₁Q₁P₂A₂, quadrilateral A₂Q₂P₃A₃, quadrilateral A₃Q₃P₄A₄, etc. Their areas are denoted as S₁, S₂, S₃, S₄, etc. **Questions:** (1) 求 S₂; (Find S₂;) (2) 直接写出 S₅ 及 S_n的值. (Directly write down the values of S₅ and S_n.)
