2.28 Geometric Sequences GCSE PowerPoint Lesson

In this 33-slide lesson, students will explore geometric sequences, where each term is found by multiplying the previous term by a constant ratio. They will practise identifying the common ratio and using it to find the next terms in a sequence. Students will learn how to generate a sequence by substituting into the geometric nth term formula. They will also develop the skills to work out the nth term of a geometric sequence, using the first term and common ratio.

The lesson includes:

• Clear, guided examples

• Discussion opportunities from Think, Pair, Share

• Mini whiteboard section to check understanding and clarify misconceptions
