This example demonstrates an arithmetic sequences practice. The core mathematical concepts involved are the definition and properties of arithmetic sequences. Using GeoGebra commands such as RandomElement, Random, and Simplify, a series of arithmetic sequences questions can be constructed. Suitable for middle and high school students to learn and practice arithmetic sequences.
