Question

Determine the geometric mean of the first eight odd numbers.

• A. $2.14$
• B. $3.14$
• C. $5.14$
• D. $6.14$

Answer 1

The correct option is D $6.14$

First eight odd numbers be $1,3,5,7,9,11,13,15$
$n=\frac{1}{8}=0.125$
Geometric mean $=(1\times 3\times 5\times 7\times 9\times 11\times 13\times 15{)}^{0.125}=6.14$
