Geometric Progression: Sum of n Terms Interactive Demo
Loading the math board and drawing, please wait…
This GeoGebra applet provides an interactive visualization and practice tool for understanding the sum of the first n terms of a geometric progression (GP). The core mathematical concepts covered include geometric sequences, the first term a, common ratio r, the number of terms n, and the formula for the partial sum Sn. Constructed using GeoGebra, the applet features sliders for parameters a, n, and r, a calculated value Sn for the sum, and multiple text objects (text1 through text7) to dynamically display the sequence terms, the sum formula, and step-by-step accumulation. It is highly suitable for high school mathematics classrooms, self-guided student exploration, and exercises aimed at building intuition for sequence summation.

AI Drawing Prompt Reference
Create an interactive geometric progression sum demo with three draggable sliders for the first term a, common ratio r, and number of terms n; automatically compute and display the partial sum Sn; and show dynamic text listing each term, the summation formula, and the step‑by‑step accumulation. The sliders update in real time, the calculated sum appears as a numeric value, and the accompanying text objects present the sequence terms, the explicit formula for Sn, and a visual breakdown of how the sum builds up term by term.
