Patterns and Sequences
Directions: Work in groups of three and turn in only one well written copy. The worksheets
will be collected with your homework tomorrow and must comply to the same standards.
Note when a problem asks to create your own example, do not use examples out of the text
but come up with your own examples.
1. Recall the arithmetic sequence introduced in class. Fill in the following table:
1 3 = 3 = 3 + 0 ·2
2 5 = 3 + 2 = 3 + 1 ·2
3 7 = (3 + 2) + 2 = 3 + 2 ·2
4 9 = (3 + 2 + 2) =
5
6
7

2. Create your own arithmetic sequence for an elementary school class.
•Create a table recording the sequence as done in 1. Include in the table the
