Find the first five terms of the sequence

This GeoGebra example demonstrates how to find the first five terms of a sequence, write an explicit formula to represent the sequence, and find a specified term. The core mathematical concepts involved include sequences, explicit formulas, and term calculation. In terms of construction, it uses the Textfield command to create input fields for user interaction, and the Max command to set parameter limits. Key objects include sliders like DirectionsSlider for adjusting sequence parameters, points such as A1, B1, etc., to visualize terms, the function f to define the sequence rule, and various text labels to display values and derivations. Objects like Derivation and FunctionalFormula help show the formula derivation. This example is suitable for high school mathematics, particularly in teaching sequences, to help students understand term finding and formula writing.
