Answer 2

Answer:

If the value in series is negative we cannot calculate the

(C) Geometric mean. As, the Geometric mean can be applied only for Positive numbers.

Explanation:

OPTION (C) Geometric mean:

• The geometric mean is a mean or average in mathematics that indicates the central tendency or typical value of a set of numbers by multiplying their values together (as opposed to the arithmetic mean which uses their sum).
• hence the correct answer is (C)

OPTION (A)

(A) Mean can be calculted if the value is negative. Hence the option is incorrect.

OPTION (B)

(B) Median can be calculted if the value is negative. Hence the option is incorrect.

OPTION (C)

(D) Harmonic mean can be calculted if the value is negative. Hence the option is incorrect.
