Average Sequence

Published on 02/14/2011

Activity Overview

In this activity, students will find the arithmetic mean between two consecutive numbers in a sequence to generate the next term and investigate the pattern that occurs.

Key Steps

  • Image

    Students will solve the average sequence problem and share what they find. First, students find the arithmetic mean between two consecutive numbers in a sequence to generate the next term.

  • Image

    Then, students use the list features and calculations to find subsequent terms in the sequence. This will help students generalize about what is happening and find the 100th term in the sequence.

    Finally, students look at a case where the first two elements in a sequence are decreasing to determine if the pattern holds.
