In a geometric sequence each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

12/3 = 4

36/12 = 3

As the ratio is not common it is not a geometric sequence.

SCM, his or her answer is not technically wrong, so it should not be flagged. However, it should be deleted because he/she did not answer the question properly.
