This lesson builds on the previous lesson introducing arithmetic sequences and series. This lesson focuses on where and how to use the formula for finding the sum of a series. It does look at some more challenging questions and when to use one formula as opposed to another, i.e. looking at efficiency.
The lesson comes with a starter, learning objectives, keywords, plenty of teaching slides/examples, questions with answers and plenary. This is part of a bigger bundle or series, which can either be purchased with or without the additional A-Level lessons.
