the mean (average) of a set of natural numbers is a straightforward process. In mathematics, natural numbers are typically defined as the positive integers starting from 1 (1, 2, 3, \dots).
To find the mean, you follow two main steps:
1. The Formula
The mean is calculated by dividing the sum of all numbers the total count of numbers in the set
Step-by-Step Example
Let’s find the mean of the first five natural numbers: 1, 2, 3, 4, and 5.
Step 1: Find the sum.
1 + 2 + 3 + 4 + 5 = 15
Step 2: Count the numbers.
There are 5 numbers in this set.
Step 3: Divide.
15 \div 5 = 3
The mean of the first five natural numbers is 3.
Special Case: Mean of the first n natural numbers
If you need to find the mean of a very large sequence (e.g., the first 100 natural numbers), you don't have to add them all manually. You can use this shortcut:
\text{Mean} = \frac{n + 1}{2}
