SEQUENCES OF REAL NUMBERS

Before beginning this unit students are expected to have already worked with real numbers, know that real numbers are represented on a straight line and know how to plot pairs of real numbers on the Cartesian plane.

This unit introduces the concept of a sequence of real numbers and shows how they can be represented on two types of graphs, one on the Cartesian plane and the other on a straight line.

• Identify the elements that form part of the definition of a sequence and its graph.

• Use the general term or nth term to find terms in a sequence.

• Draw the graph of a sequence given by its general term or nth term on the plane.

• Draw the graph of a sequence given by its general term or nth term on the real line.
