The IB syllabus includes the following notes:

Spreadsheets, GDCs and graphing software may be used to generate and display sequences in several ways. If technology is used in examinations, students will be expected to identify the first term and the common difference.

Examples of applications include simple interest over a number of years.

Analysis, interpretation and prediction where a model is not perfectly arithmetic in real life. Students will need to approximate common differences.

If you use a TI-Nspire GDC there are instructions here for generating a sequence on the calculator.
