Derive and use the finite geometric series formula to solve problems such as mortgage-payment models.

Build a finite geometric-series model for a loan balance after repeated end-of-period payments

Problem

Write the loan-balance model after \(8~\text{end}\text{-}\text{of}\text{-}\text{period}~\text{payments}\) for principal \(8000\), periodic growth factor \(1.02\), and payment \(300\).

Loan cash-flow timeline with principal 8000 at time zero and eight equal negative 300 dollar end-of-period payments; every scheduled payment is negative. Open full size
