Best Answer

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.

An arithmetic-geometric mean is a mean of two numbers which is the common limit of a pair of sequences, whose terms are defined by taking the arithmetic and geometric means of the previous pair of terms.

'Geometric' is an adjective, as it is used to describe something, e.g. a geometric shape. It is based on the noun 'geometry'.

They are both adjectives. The first relates to geometry and the second to arithmetic.

It is a geometric sequence.
