Is the sequence 6, 3,0, -3, -6, -9,... arithmetic, geometric, or neither? Complete the explanation. Write a recursive rule for the sequence.

The sequence is(geometric/arithmetic/neither)bec ause(it does not have a common difference or ratio/it has a common ratio of 3/it has a common difference of -3)
f(1) =; f(n) =
