The sum of the first n natural numbers is given by the formula:
scss
S = n(n+1)/2
where S is the sum of the first n natural numbers.
For example, if we want to find the sum of the first 5 natural numbers, we can use the formula as follows:
scss
S = 5(5+1)/2
= 5(6)/2
= 15
So the sum of the first 5 natural numbers is 15.
What is Required Sum of the first n natural numbers
I believe you may be asking for an explanation of the formula for the sum of the first n natural numbers. Here it is:
Consider the sum of the first n natural numbers:
makefile
S = 1 + 2 + 3 + ... + n
We can also write this sum in reverse order:
scss
S = n + (n-1) + (n-2) + ... + 1
If we add these two equations, we get:
scss
2S = (1+n) + (2+n-1) + (3+n-2) + ... + (n+1)
Notice that each term in the parentheses has a sum of (n+1). There are n terms in the sum, so we have:
scss
2S = n(n+1)
Dividing both sides by 2, we get the formula:
scss
S = n(n+1)/2
So that is how we get the formula for the sum of the first n natural numbers.

Case Study: Finding the Sum of the First n Natural Numbers
Problem: Find the sum of the first 20 natural numbers.
Solution:
The sum of the first n natural numbers can be found using the formula:
S = n(n+1)/2

Abstract: The sum of the first n natural numbers is a fundamental concept in mathematics that has many practical applications in various fields. In this white paper, we will explore the algebraic formula for the sum of the first n natural numbers and understand its derivation and applications.

Introduction: The sum of the first n natural numbers is a sequence of integers that starts from 1 and goes up to n. This sequence can be represented as 1, 2, 3, …, n-1, n. The sum of this sequence is a common problem in mathematics, and can be found using various methods. One of the most common methods is the algebraic formula, which provides a simple and efficient way to calculate the sum of the first n natural numbers.
Derivation of the Formula: The algebraic formula for the sum of the first n natural numbers is given by:
S = n(n+1)/2
where S represents the sum of the first n natural numbers. To derive this formula, we can use the concept of arithmetic series. An arithmetic series is a sequence of numbers where each term is obtained by adding a constant value (called the common difference) to the previous term.
For the sequence of the first n natural numbers, the common difference is 1. Therefore, the sum of the first n natural numbers can be expressed as:
S = 1 + 2 + 3 + … + (n-1) + n
= n + (n-1) + (n-2) + … + 2 + 1
If we add the corresponding terms of these two expressions, we get:
2S = (n+1) + (n+1) + (n+1) + … + (n+1) + (n+1)
where there are n terms of (n+1). Simplifying this expression, we get:
2S = n(n+1)
Dividing both sides by 2, we get the algebraic formula for the sum of the first n natural numbers:
S = n(n+1)/2
Applications of the Formula: The formula for the sum of the first n natural numbers has many practical applications in mathematics and other fields. Some of its applications are as follows:
- In computing, the formula is used to calculate the total cost of n items that are priced consecutively.
- In statistics, the formula is used to calculate the mean (average) of the first n integers.
- In physics, the formula is used to calculate the total distance covered by a moving object in n units of time, where the velocity is constant.
- In finance, the formula is used to calculate the total interest earned on a sum of money that is invested for n years, where the interest rate is constant.
Conclusion: In conclusion, the algebraic formula for the sum of the first n natural numbers is a fundamental concept in mathematics that has many practical applications in various fields. The formula can be derived using the concept of arithmetic series, and provides a simple and efficient way to calculate the sum of the first n natural numbers.
