💡 Analysis & Explanation
Mathematical Definition
The sequence of natural numbers begins strictly at 1. Therefore, the first 10 natural numbers range continuously from 1 to 10.
Summation Formula
The aggregate sum of the first 'n' natural numbers is derived rapidly using the standard arithmetic progression formula: Sum = n(n+1)/2. Injecting n=10 yields (10 * 11) / 2 = 55.
Average Computation Concept
To ascertain the mean, the total calculated sum must be divided evenly across the total count of variables.
Final Execution
Dividing the sum (55) by the count (10) outputs the fraction 55/10.
Conclusion
The resulting decimal evaluation flawlessly stands at 5.5.
