Question

What is the geometric mean of 2, 4 and 8?

• A. 4.67
• B. 3.43
• C. 4
• D. 4.5

Hint:

The geometric mean is useful when you need to find the average rate of growth or the average of multiplicative quantities. It is calculated by taking the nth root of the product of all values.

Answer 1

The Correct Option is C

The geometric mean of a set of numbers is given by the formula: Geometric Mean = n√(x₁ · x₂ · · xₙ) where n is the number of values, and x₁, x₂, , xₙ are the values in the set. For the numbers 2, 4, and 8, the geometric mean is calculated as: Geometric Mean = 3√(2 · 4 · 8) Geometric Mean = 3√(64) = 4 The geometric mean of 2, 4, and 8 is 4. 

Final Answer: (C) 4.
