Overview

A sequence arranged according to a certain rule is called a sequence, and one that follows a certain rule is called a progression. Arithmetic progression and geometric progression are two important special types of progressions. An arithmetic progression has a constant difference between consecutive

Key Concepts

A sequence arranged according to

A sequence arranged according to a certain rule is called a sequence. A sequence that follows a certain rule is called a progression.

A progression is called an arithmetic

A progression is called an arithmetic progression if the difference of two consecutive terms is constant. The general form is a, a+d, a+2d, a+3d, ...

The common difference of an

The common difference of an A.P. is the difference of two consecutive terms. It is represented by d and is calculated as d = T2 - T1 = T3 - T2 = ... =

The general term of an arithmetic

The general term of an arithmetic progression is Tn = a + (n-1)d, where a is the first term and d is the common difference.

If an

If an A.P. has n terms and last term l, then l = a + (n-1)d. The nth term from the end is l - (n-1)d.

Learning Objectives

  • Identify a sequence and a progression
  • Recognize arithmetic progression and geometric progression
  • Find the common difference of an A.P.
  • Find the common ratio of a G.P.
