3.  A sequence is a list of numbers in a particular order.  Each number in a sequence is called a term.  An arithmetic sequence is when each term is found by adding a constant (called the common difference) to the previous term.

4.  a n = nth term  a 1 = first term  d = common difference  n is any positive integer

5.  Find the indicated term

7.  Write an equation for the nth term of the series 11, 15, 19, 23, …

8.  Write an equation for the nth term of the series 33, 25, 17, 9, …

9.  The terms between any two non-successive terms are called arithmetic means.

10.  Find the 3 arithmetic means between 12 and 40

11.  Find the two arithmetic means between 25 and -14
