Arithmetic Sequences

Now, let's go backwards!!! Given the explicit formula, list the first five terms in order. (You can ignore term 0)

• 2, 5, 8, 11, 14, ...

• 3, 1, -1, -3, -5, ...

• 3, 6, 9, 12, 15, ...

• 3, 5, 7, 9, 11, ...

An arithmetic sequence is an example of a linear function.

• True, because having a common difference also means it has a constant rate of change

• False, because it's not shown on a graph
