CHAPTER AT A GLANCE
Predicting What Comes Next: Sequences and Progressions
•Unit: Algebra
•Board weightage: Sequences and progressions give regular 2-mark and 3-mark questions on the nth term and the sum of natural numbers (please check the latest sample paper)
•Key ideas from the textbook: explicit and recursive rules, Arithmetic Progression, Geometric Progression, sum of the first n natural numbers, Sierpiński fractals
•Most scoring part: finding the nth term and the number of terms of an Arithmetic Progression or a Geometric Progression
•Time to revise: about 60 minutes
