  1. Sect 7.2: Arithmetic Sequence An arithmetic sequence is a pattern of numbers such that to get from one term to the next, you ADD the same value.

  2. Examples of Arithmetic Sequences:

  3. Find the 10th term…100th term… 249th term…

  4. Arithmetic Sequence Ex: The first three terms are 20, 16.5, and 13.

  5. Ex: Find the 5th term, 10th term, and the nth term of the sequence: 16, 13, 10, 7, …

  6. Ex: If a4 = 5 and a9 = 20, find a6.

  7. Partial Sums of an Arithmetic Sequence Ex: Find the sum of all the integers from 1 to 100.
