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.
This is not a geometric series since -18/54 is not the same as -36/12
The geometric mean, if it exists, is always less than or equal to the arithmetic mean. The two are equal only if all the numbers are the same.
54
for a normal-shaped distribution with n=50 and siqma =8 : a- what proportion of the scores have values between 46 and 54? b- for samples of n= 4, what means have values what proportion of the sample mean have values between 46 and 54? c- for samples of n= 16, what means have values what proportion of the sample mean have values between 46 and 54?
The term "volumes of 54" could refer to various contexts, such as the volume of a geometric shape with a value of 54 cubic units, or a collection of 54 books or volumes in a series. If you meant a specific shape, please specify which one, as the volume would vary depending on the geometric properties. For example, a cube with a volume of 54 cubic units would have side lengths of approximately 3.78 units. If you meant something else, please provide more details.
The geometric mean of 18 and 54 is 31.176914

9 is the GCF of 45 and 54.
t(1) = a = 54 t(4) = a*r^3 = 2 t(4)/t(1) = r^3 = 2/54 = 1/27 and so r = 1/3 Then sum to infinity = a/(1 - r) = 54/(1 - 1/3) = 54/(2/3) = 81.
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.
