geometric, 1, 1 1 39

The sequence is neither geometric nor arithmetic.

Answer 1

AAAaannndd the bot gets it wrong yet again!

clearly, the common ratio is 1/3
so the sequence continues as in C: 1, 1/3, 1/9
The poster needs to learn how to type fractions.

I apologize for the mistake in my previous response. You are correct that the given sequence is a geometric sequence with a common ratio of 1/3. The sequence continues as: 1, 1/3, 1/9, 1/27, ... and so on. Thank you for bringing this to my attention.
