Question

What is the mean of the first five whole numbers?

• A. 0
• B. 3
• C. 5
• D. 2

Answer 1

The correct option is D 2

The first five whole numbers are: 0, 1, 2, 3 and 4.

Total number of numbers = 5.

Sum of numbers = 0 + 1 + 2 + 3 + 4 = 10

Thus, the mean of first five numbers = $\frac{\text{Sum of numbers}}{\text{total number of numbers}}$

⇒ Mean of first five numbers = $\frac{10}{5}$

⇒ Mean of first five numbers = 2
