Verified Answer :

set up a proportion putting x in the means location

6/x=x/20
cross multiply
x^2= 120
x= square root of 120
10.95 or 2 square root of 30

The geometric mean between 6 and 20 is;10.95

Geometric mean

According to the question;

  • We are required to determine the geometric mean between 6 and 20.

Hence, geometric mean of both numbers can be evaluated as follows;

  • G.M = √6 × 20

  • G.M = √120.

  • G.M = 10.95.
