It is neither.
(-6) - (-2) = -4
(-18) - (-6) = -12 which is not the same as -4.
Therefore it is not an arithmetic progression - which requires the difference between successive terms to be the same.
Also
-162/-54 = 3
-468/-162 = 2.88... recurring, and that is not the same as 3.
Therefore it is not a geometric progression - which requires the ratio of terms to be the same.
