Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Sequences and Their Terms, 2. Series and Sigma Notation, 3. Geometric Progression and General Term.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 126 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Sequences and Series after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • A sequence is ordered and follows a rule.
  • The nth term is the general term.
  • A finite sequence has a limited number of terms.
  • A series is the sum of terms of a sequence.
  • Sigma notation is a compact way to write sums.
  • The expression and its numerical sum are not the same thing.
  • In a G.P., the ratio between consecutive terms is constant.
  • Every term of a G.P. must be non-zero.
  • The first term is a and the common ratio is r.

Common Mistakes to Avoid

A sequence and a series mean the same thing.

The nth term is always the sum of the first n terms.

Every sequence must have a neat formula for its nth term.

Memory Tips

Sequence as ordered terms

Nth term as general term

Finite and infinite sequence

Sequence as a function
