Using a recurrence relation to generate and analyse a geometric sequence | Year 11 General Maths

**

This video is another in the series relating to sequences for the Year 11 General Maths Units 1 and 2 course. Using the ideas of what a geometric sequence is, we can now make sure to learn the difference between a rule and a recurrence relationship (otherwise known as a term-to-term rule). As this is a pretty short video, I look at how to read a recurrence relationship and how to then use it to generate sequences. There are some worked examples and they are all explained in an easy to understand way.

This maths video has been created for courses which are delivered in Australia but, as Maths is a constant, it is equally helpful for students in the USA, UK and other countries who are looking for good maths videos for both high school and middle school.
