Question

Using python

Write a Python function called sgm that requests a positive integer n and returns the series geometric mean of the numbers 1,2,3, . . . n. For example sgm(5) =

(5 x 4 x 3 x 2 x 1)^1/5 = (120) ^1/5 = 2.605 . Write the program so that a user is requested for a positive integer and program prints the series geometric mean of the integer.

Example execution:

Enter number: 5

series geometric mean of 5  = 2.605 

Answer 1

Here is the simple python program to find the gm

=========================================================================================

def sgm(n):
    product=1
    for i in range(1,n+1):
        product=i*product
    return product**(1.0/n)

n=int(input('Enter number: '))
print('Series geometric mean of {0} = {1}'.format(n,round(sgm(n),3)))
