Using a recurrence relation to model an investment annuity and calculating interest accrued

Developing recursion relations to model investment annuity scenarios and calculating interest earned in both the deposit and withdrawal phases. Includes practice SF and CF questions for Unit 4 12 General Maths in QLD with worked solutions.
Lesson objectives:
- Use recursion relation to model to the balance of an investment annuity after n compounding periods
- Calculate the total amount of interest earned since the initial investment balance (A0) was made, after n compounding periods
- Solving problems involving investment annuities using recurrence relations and interest calculations
