💡 Analysis & Explanation
Whole Number Sequence
Whole numbers begin exactly at 0. Therefore, the first 14 whole numbers are the integers from 0 up to 13.
Summation Logic
The sum of numbers from 0 to 13 is identical to the sum of the first 13 natural numbers. Using the formula n(n+1)/2, we get (13 × 14) / 2 = 91.
Average Calculation
To find the average, divide this total sum (91) by the total count of numbers (14). 91 / 14 equals 6.5.
Conclusion
The average value is indeed 6.5.
