Step-by-step explanation:

Answer 2

A)Geometric mean and Harmonic mean cannot be calculated when one of numbers in the series is zero.

• "In mathematics, the geometric mean is generally defined as a mean, which indicates the central tendency of a set of numbers by using the product of their values."

                                                    $c = \sqrt{ab}$

where,

C is the geometric mean of a and b.

• "The harmonic mean is generally defined as a mean which is a type of numerical average. The harmonic mean is the reciprocal of the arithmetic mean of the reciprocals."

                                         C = 2ab/(a+b)

Where,

C is the harmonic mean of a and b.

• When one of the numbers is zero, geometric mean will become zero and the harmonic mean also becomes zero. Hence , averages cannot be calculated.
