What are some applications of arithmetic progression?

Arithmetic progression (AP) has various applications across different fields. In finance, it can be used to model fixed payment plans, such as loan repayments or savings plans where payments are made at regular intervals. In computer science, AP is often utilized in algorithms to analyze time complexity or in data structure designs, such as indexed data retrieval. Additionally, it's applied in physics and engineering to describe uniform motion and in statistics to analyze data trends.
