Overview

An arithmetic progression is a list of numbers in which each term is obtained by adding a fixed number to the preceding term except the first term. That fixed number is called the common difference. An AP can increase, decrease, or remain constant, depending on whether the common difference is posit

Key Concepts

A sequence in which every term

A sequence in which every term after the first is found by adding a fixed number to the previous term. The general form is a, a + d, a + 2d, a + 3d, .

To know an AP completely

To know an AP completely, both the first term a and the common difference d are needed. The common difference is found by subtracting a term from the

The nth term is given by

The nth term is given by a_n = a + (n - 1) d. This formula gives any term directly without writing all the terms before it.

The sum of the first n

The sum of the first n terms of an AP is S = n/2[2a + (n - 1) d]. If the first and last terms are known, S = n/2(a + l) is used.

The nth term can also be

The nth term can also be written as a_n = S_n - S_{n-1}.

Learning Objectives

  • Identify whether a list of numbers forms an arithmetic progression.
  • Find the first term and common difference of an AP.
  • Write the general form of an AP.
  • Find the nth term of an AP using a_n = a + (n - 1) d.
  • Find the sum of the first n terms of an AP using S = n/2[2a + (n - 1) d] and S = n/2(a + l).
