    Is \(\rm 2nd ~term - 1st~ term\) equal to \(\rm 3rd~term - 2nd~term\)? If yes, then it's arithmetic.

    it is not arithmetic sequence A sequence is arithmetic if the difference between its any two consecutive terms is same. in your question it could be arithmetic if 3-1=9-3=27-9=81-27 but as they are not equal so it is not arithmetic
