This video is the next in the Sequences series of lessons for the General Maths Units 1 and 2 course. Having looked at the basics of arithmetic sequences, we now look at the different ways of writing a sequence. One of the most important for the General Maths Units 3 and 4 course will be the knowledge of how to write a recurrence relationship. These are a way of writing both arithmetic and geometric sequence and are used a lot. I show how to read them and use them in a range of questions.
