Year 13/A2 Pure Chapter 3.1 (Sequences and Series)

This first lesson on Year 13 Pure Chapter 3 (Sequences and Series) begins by revisiting arithmetic series concepts from GCSE in warm-up questions 3 and 4. From there, we use this as a basis to introduce the "A-Level version" of the nth-term formula for an arithmetic series, followed by some exam-type worked examples. This lesson is meant as preparation for Exercise 3A, page 61 of the Pearson Edexcel Pure Mathematics Year 2/A2 Textbook. #sequences #series #sequencesandseries Introduction: 00:00 Solution to Warm-Up Q1: 1:17 Solution to Warm-Up Q2: 8:12 Solution to Warm-Up Q3: 14:56 Solution to Warm-Up Q4: 17:37 ARITHMETIC SEQUENCES Introduction: 19:49 Worked Example 1: 20:21 Worked Example 2: 24:19 Worked Example 3: 27:20 Suggested exercises: 33:50
