Look 2 and 8, their geometric mean is square root of 16 which is 4 and between 2 and 54. 9 and 4 have a geometric mean of 6 which is also between 2 and 54. Is this what you mean? Pun intended... The geometric mean of 2 and 54 is square root of 108.

54

54, 54, 54, 54, 54, 54, 54, 54, 54, 84 The median is clearly 54. The mean is ((54*9)+84)/10 = 57.

18

Arithmetic, you ADD the same number each time, eg. 2, 5, 8, 11 etc. Geometric, you MULTIPLY by the same number each time, eg. 2, 6, 18, 54 etc.

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.

If you mean 6, 18, 54 then the 6th term is 1456 because each term is 3 times greater than the previous term

This is not a geometric series since -18/54 is not the same as -36/12

66 is greater than 54.

GM(6, 9) = sqrt(6*9) = sqrt(54) = 7.3485 approx.

652 is greater than 54.

54

Yes, 56 is greater than 54.
