💡 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.
