Interactive Demo: Arithmetic Sequence General Term and Sum Formulas

2020-03-11 12:00
This GeoGebra applet dynamically demonstrates the core formulas of arithmetic sequences: the general term formula aₙ = a₁ + (n-1)d and the sum of the first n terms Sₙ = na₁ + n(n-1)d/2. Interactive sliders allow real-time adjustment of the first term a₁, common difference d, and number of terms n, enabling observation of how sequence terms and their sum change. The Sequence command generates terms
