There are many tests that you have learned for this course, and we are headed to the final one, the **ratio test**, which is useful for series with **exponentials **or **factorials**.

Now that we have completed all the tests that you need to know for the AP Calculus BC test, here is a flowchart showing how to use the tests (ignore the Taylor Series, which we will talk about later, and the root test, which is not required for this course).

For a better resolution, check out this link.

1. State the ratio test.

Determine if the following series converge or diverge.
