Arithmetic Sequences and Series

Activity Overview

In this activity, students will explore arithmetic sequences and series. They will consider the
effect of the value for the common difference and first term using Lists and Spreadsheets on the  TI-Nspire™ CX II. Finally, they will graphically analyze the arithmetic series using graphs.

Key Steps

Step 1

Students will use formulas to find the differences of the consecutive terms of a sequence.

Step 2

Students will move to page 2.1 and generate a sequence in Column B to display the first 30 terms.

Step 3

In part 3, students will practice finding the sum of a series.
