The average of first 14 whole numbers is:

Correct option is A

Given:

The first 14 whole numbers are $$0, 1, 2, 3, \ldots, 13$$​​

Formula Used:

Average = $$\frac{\text{Sum of the numbers}}{\text{Total number of numbers}}$$

The sum of the first n whole numbers (from 0 to n-1):

Sum = $$\frac{n(n-1)}{2}$$​​

​Solution:

For the first 14 whole numbers:

Sum = $$\frac{14(14-1)}{2} = \frac{14 \times 13}{2} = \frac{182}{2} = 91$$​​

Average = $$\frac{91}{14}$$​ = 6.5
