If geometric means be inserted between and then the geometric mean will be
Explanation for the correct option
Step 1: Solve for common ratio
Given that geometric means be inserted between and
Let the geometric means be
Then the series will be
Number of terms in the series is
We know that the term of a G.P. is where is the first term and is the common ratio.
For the given series,
Step 2: Solve for the required value
Hence the correct option is option(C) i.e.
