Arithmetic sequences have a common difference while geometric sequences have common ratio.
Let's check whether the terms have a common difference.

As we can see, each term doesn't have the same difference, hence, they don't have a common difference and thus, the given is not an arithmetic sequence.
Now, let's check whether they have a common ratio by dividing the term by its previous term.

As we can see above, they don't have a common ratio, hence, the given is not a geometric sequence.
Therefore, the given sequence is neither arithmetic nor geometric sequence.
