Geometric sequence applications | Year 11 General Maths | MaffsGuru.com ** This video is the next video in the series looking at sequences. It is important to understand the difference between a rule and a recurrence relationship. This video looks at how we can find the nth term of a geometric sequence and how we can use it to find an term in the list. Knowing how to relate a common ratio and percentage increase or decrease is a handy skill which is used a lot in General Maths Units 3 and 4. The video is explained in my usual manner ensuring that it is easy to follow with lots and lots of worked examples. There is also an example of how we can apply this learning in real life using geometric sequences. ** 00:00 Introduction 00:07 Welcome 00:47 Learning Objectives 01:06 Recap of past learning 02:06 Finding the nth term of a geometric sequence 04:45 Finding the nth term of a geometric sequence: The Formula 05:03 Example: Finding the nth term of a geometric sequence 06:41 Turning percentage change into a common ratio 08:20 Example: Turning percentage change into a common ratio 09:24 Example 2: Turining percentage change into a common ratio 10:24 Rule for turning percentage change into a common ratio 11:24 Example: Calculating the common ratio for a given percentage change 14:05 Example: Application question 17:17 Final words 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.
