4. Arithmetic Sequences Add by a common difference to get the next term
3, 6, 9, 12, 15, ...
20, 18, 16, 14, 12, ...
Remind them of the formula from Math 1. Write the rules for the two examples in class.

5. Geometric Sequences Multiply by a common ratio to get the next term
1, 2, 4, 8, 16, ...
27, 9, 3, 1, 1/3, ...

6. the nth term
the first term
the common ratio;
the number of the term you seek (i.e., if you want the 4th term, use a 4)
