Recognising Special Sequences

In this lesson
In this video you'll learn about recognising special sequences for GCSE Maths, with worked examples and the mistakes examiners report. By the end you'll be able to recognise a sequence as belonging to a special family (square, triangular, cube, Fibonacci-type, quadratic, or simple geometric) and state the generalising rule that produces it.

For teachers
This GCSE Maths lesson teaches recognising special sequences. By the end, students should be able to recognise a sequence as belonging to a special family (square, triangular, cube, Fibonacci-type, quadratic, or simple geometric) and state the generalising rule that produces it. It works through two worked examples and the mistakes examiners report.
