A complete, ready-to-teach PowerPoint lesson on arithmetic sequences for Pearson Edexcel International A Level Pure Mathematics 2 (WMA12). It covers arithmetic sequences, starting with where a + (n − 1)d comes from. Students use the nth term, find the first negative term, count the terms in a sequence, find a and d from two terms and solve problems with algebraic terms.

What’s included (21 slides):

• Learning objectives, prior knowledge and key words
• 5-minute retrieval starter
• Explanation slides: Where does a + (n − 1)d come from?; Arithmetic sequences
• 5 worked examples, built up one step per click, each followed by a “You Do” question with a full worked solution
• Common mistakes slide
• Practice questions with answers
• Exam-style question (5 marks) with full mark scheme
• Exit ticket and “Can I…” checklist
• Speaker notes on every slide
