Solved Examples and Exercises in Sequences and Progressions
The chapter gives in-text solved examples first, then exercise sets to practise. Read the solved examples before you try each set.
- Exercises 8.1 to 8.3: three sets covering patterns, the nth term, and sums.
- End-of-Chapter Exercises: mixed problems that pull the whole chapter together.
- In-text solved examples: step-by-step models placed through the chapter text.
What Changed in the 2026-27 Sequences and Progressions Chapter
This chapter comes from the new Ganita Manjari book, which replaces the old 15-chapter NCERT Maths book. The new book is activity-based, so sequences begin with real patterns like stacked bricks before any formula. Arithmetic progressions used to appear only in Class 10. Bringing a friendly Chapter 8 into Class 9 gives you an early, gentle start on APs and their sums.
How to Read the Sequences and Progressions Chapter
Read the Class 9 Maths Book PDF Chapter 8 Sequences and Progressions with a notebook to write out each pattern. Skim once to see the flow, then read slowly and extend every sequence by a few terms. Work through the solved examples, and only then try the exercises. This skim, then detail, then examples, then exercises order makes the nth term clear.
