This is another video in the series relating to modelling growth and decay using recursion. Taking a look at how we can change from a recurrence relation to a rule for linear growth and decay, I show how this can save time and be applied to a range of finance applications. I once again look at interest and depreciation in terms of simple interest, flat rate depreciation and unit cost depreciation. There are lots of worked examples all sourced from the Cambridge VCE textbook series (with permission). Theory is explained in an easy to understand way.
