About this lesson
This is the next video in the VCE General Maths series looking at modelling growth and decay using recursion. In this video I am going to look at how we can model geometric growth and decay using recurrence relationships. I go through what the recurrence relationship looks like before moving onto applying it to real world examples such as compound interest and reducing balance depreciation. I also take time to recap the work to allow us to convert from percentage increase and decrease to multipliers. There are lots of worked examples (thanks to Cambridge VCE Textbooks) and VCAA exam questions.
