In this lesson
In this video you'll learn about nth term of a linear sequence for GCSE Maths, with worked examples and the mistakes examiners report. By the end you'll be able to deduce an algebraic expression for the nth term of a linear sequence, correctly distinguishing it from the term-to-term rule.

For teachers
This GCSE Maths lesson teaches finding the nth term of a linear sequence. By the end, students should be able to deduce an algebraic expression for the nth term of a linear sequence, correctly distinguishing it from the term-to-term rule. It works through three worked examples and the mistakes examiners report.
