IB Math AI SL 1.2 – Arithmetic Sequences

Topic: Number and Algebra
Level: IB Mathematics: Applications and Interpretation (SL)
File Type: Editable Slides / Worksheet

Overview

This resource introduces Arithmetic Sequences, a key concept in IB Math AI SL Topic 1.2.
It helps students recognize numerical patterns, calculate sequence terms, and find the sum of arithmetic progressions.

Students will learn to determine whether a sequence follows a pattern, identify the nth term and the common difference, and calculate the sum of n terms. The lesson also introduces a connection between arithmetic sequences and simple interest calculations.

Learning Objectives

By the end of this lesson, students will be able to:

  • Identify and describe arithmetic sequences.
  • Determine whether a sequence follows a constant pattern.
  • Find the nth term and the common difference of a sequence.
  • Derive and apply the formula for the sum of n terms in an arithmetic sequence.
  • Apply arithmetic sequence concepts to solve real-world problems involving simple interest.

What’s Included

  • Lesson slides formatted in clear, structured sections using Arial font (45 pt and 35 pt).
  • Review of prerequisite knowledge on solving simultaneous equations.
  • Step-by-step explanation of arithmetic sequences and their formulas.
  • Worked proofs showing how the formula for the sum of n terms is derived.
  • Practice problems with guided solutions using elimination and substitution methods.
  • Simple interest example problems linked to arithmetic progressions.

Topics Covered

  • Definition and structure of sequences.
  • Identifying arithmetic sequences and patterns.
  • nth term and common difference formula.
  • Derivation of the sum of n terms formula.
  • Applications of arithmetic sequences in finance (simple interest).
  • Worked examples and full solutions.

Why You’ll Love It

  • Visually clear and IB-aligned formatting ideal for projection or print.
  • Logical, scaffolded lesson flow from definition to application.
  • Reinforces algebraic problem-solving and pattern recognition skills.
  • Connects mathematical theory to practical examples involving finance.
  • Perfect for classroom teaching, revision sessions, or student self-study.
