The ratios are not constant, so sequence is not geometric.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/step2.JPG\")
Find the difference of consecutive terms.

There is no common difference, so the sequence is not arithmetic.
\Thus, the sequence is neither geometric nor arithmetic.
