By the definition, the geometric mean x of any two. numbers a and b is given by. Therefore, the geometric mean of 5 and 20 is. ANSWER: 10.
The geometric mean is the nth n t h root when you multiply n numbers. For example, if you multiply three numbers, the geometric mean is the third root of the product of those three numbers. The geometric mean of five numbers is the fifth root of their product.
When a positive value is repeated in either the means or extremes position of a proportion, that value is referred to as a geometric mean (or mean proportional) between the other two values. … The geometric mean between 4 and 25 is 10.
|Geometric Mean of 4/5 and 2||1.4|
|Geometric Mean of 25 and 35||30|
|Geometric Mean of 9 and 25||17|
|Geometric Mean of 2 and 32||17|
|Geometric Mean of 14 and 20||17|
Let a1,a2,a3 be the 3 geometric mean between 1 and 256. ∴1,a1,a2,a3,256 are in GP .
The geometric mean, sometimes referred to as compounded annual growth rate or time-weighted rate of return, is the average rate of return of a set of values calculated using the products of the terms. … Geometric means will always be slightly smaller than the arithmetic mean, which is a simple average.
or, G. M. = (π i = 1n xi) 1⁄n = n√( x1, x2, … , xn). The geometric mean of two numbers, say x, and y is the square root of their product x×y.
What Is the Geometric Mean? In statistics, the geometric mean is calculated by raising the product of a series of numbers to the inverse of the total length of the series. The geometric mean is most useful when numbers in the series are not independent of each other or if numbers tend to make large fluctuations.

|G.M of X=¯X=Antilog(∑logxn)||G.M of X=¯X=Antilog(∑flogx∑f)|
So, the three geometric means between 1 and 256 are 4, 16 and 64, the third being 64.
The geometric mean of 6 and 10 is ≈7.746 .
Now the product of 4 and 16 is 64. The geometric mean is given by the root of the product of the two numbers. So the geometric mean of 4 and 16 will be the root of 64. Thus 8 is the geometric mean of 4 and 16.
So, GM =(8x24x40)^(1/3) =7680^(1/3) = 19.72. So the GM of the given numbers is 19.72.
It’s called geometric because it deals with the product of a sequence (where an arithmetic mean deals with the sum).

gm (gram): The abbreviation gm stands for gram, a unit of measurement of weight and mass in the metric system. In weight, a gram is equal to a thousandth of a kilogram. In mass, a gram is equal to a thousandth of a liter (one cubic centimeter) of water at 4 degrees centigrade.
Geometric Mean Definition
For example: for a given set of two numbers such as 8 and 1, the geometric mean is equal to √(8×1) = √8 = 2√2.
hence the geometric mean of 9 and 16 is 12.
