The arithmetic mean is simply (7+21)sqrt(3)/2 = 14sqrt(3) = 24.25 (to 2 d.p.) The geometric mean is sqrt [ 7sqrt(3) x 21sqrt(3) ] = sqrt [ 7 x 21 x 3 ] = sqrt [21 x 21] = 21

What Is The Average Mean Of 3 Numbers That's 21?
The mean is generally the same as the average. (there are the geometric and harmonic means, but they need not concern most people here). The mean of 3 numbers, each of which is 21, is also 21.

Arithmetic
What is the Formula for arithmetic mean?
The arithmetic mean is the average of all values. Add all of the values together and divide by the number of values.Suppose you want to find the arithmetic mean of n numbers, which are x1, x2, x3, ... , xn.Then the arithmetic mean = (x1 + x2 + x3 + ... + xn)/n , that is, the sum of all the values whose mean you want, divided by the number of values.Example: values 2, 8, 11The sum of the three is 21, divided by three gives the mean = 7
What is a 'series' mean in math?
A series is a sequence of numbers that follows an identifiable pattern. There are two basic forms of series: Arithmetic, where the difference between successive terms is the same number. 1, 4, 7, 10, 13, 16, 19, 21 is an arithmetic series, each successive term is 3 larger than the previous term Geometric, were successive terms are achieved by multiplying each term by the same number 1, 2, 4, 8, 16, 32, 64, 128 is a geometric series, each successive term is the result of multiplying the previous term by 2
What is the geometric mean of 3 and 21?
Geometric Mean of two values is the square root of their product, in this case sqrt(3 x 21) ie sqrt 63, which is a whisker under 8, actually 7.94 to nearest hundredth, giving a common ratio of 2.646. 3 x 2.646 = 7.938, 7.938 x 2.646 = 21.004
What does AM mean in math?
One meaning could be "Arithmetic Mean". Thus is you have a sample set containing number say 1, 4, 5, 2, 7, 9, 21, 12, then the Arithmetic mean would be the sum of the numbers divided by the number of numbers. In this case it would be (1 + 4 + 5 + 2 + 7 + 9+ 21 + 12)/8 = 61/8 = 7 and 5/8
In arithmetic 3 times 7 equals?
I think it is 21?
What is the arithmetic mean of the first nine composite numbers that are greater than 10?
To get the arithmetic mean, sum them up and divide by the count (in this case 10). So we have 12 + 14 + 15 + 16 + 18 + 20 + 21 + 22 + 24 + 25 = 187. Divide by 10 is 18.7
