Arithmetic Sequence Calculation Practice
2020-04-22 06:24
This GeoGebra applet is an interactive exercise tool for practicing arithmetic sequence calculations. It uses RandomElement and Shuffle commands to randomly generate the first term and common difference, and the Sequence command to produce sequence terms. Students fill in subsequent terms (a1 to a5) via input boxes and submit answers using buttons for automatic verification (checka1 to checka5). T
