Introduction

Arithmetic Progression (AP) is a fundamental concept in mathematics that deals with a sequence of numbers in which each term after the first is obtained by adding a fixed constant to the previous term. This constant is called the common difference. In this article, we will explore the concept of AP, its properties, and how to solve problems related to it.

What is Arithmetic Progression?

Arithmetic Progression is a sequence of numbers in which each term after the first is obtained by adding a fixed constant to the previous term. The general form of an AP is:

a, a + d, a + 2d, a + 3d, ...

where 'a' is the first term and 'd' is the common difference.

Properties of Arithmetic Progression

There are several properties of AP that are essential to understand:

Common Difference: The common difference is the constant that is added to each term to obtain the next term.
First Term: The first term is the first number in the sequence.
Last Term: The last term is the last number in the sequence.
Number of Terms: The number of terms in the sequence is the total number of numbers in the sequence.

Example of Arithmetic Progression

Let's consider an example of an AP: 2, 5, 8, 11, ...

In this example, the first term is 2, the common difference is 3, and the number of terms is 4.

Problem: If 2n - 5, 2n - 8, 2n - 11 are in AP, then find the value of n.

To solve this problem, we need to use the properties of AP. Since the three terms are in AP, we can write:

(2n - 8) - (2n - 5) = (2n - 11) - (2n - 8)

Simplifying the equation, we get:

-3 = -3

This equation is true for all values of n. However, we need to find a specific value of n that satisfies the given condition.

Solution

To find the value of n, we can use the fact that the common difference between the first two terms is equal to the common difference between the last two terms. We can write:

(2n - 8) - (2n - 5) = (2n - 11) - (2n - 8)

Simplifying the equation, we get:

-3 = -3

However, we can also write:

(2n - 8) - (2n - 5) = 3

Simplifying the equation, we get:

-3 = 3

This equation is not true. However, we can write:

(2n - 8) - (2n - 5) = 3

-3 = 3

Introduction

Arithmetic Progression (AP) is a fundamental concept in mathematics that deals with a sequence of numbers in which each term after the first is obtained by adding a fixed constant to the previous term. In this article, we will answer some frequently asked questions related to AP.

Q: What is Arithmetic Progression?

A: Arithmetic Progression is a sequence of numbers in which each term after the first is obtained by adding a fixed constant to the previous term.

Q: What are the properties of Arithmetic Progression?

A: The properties of AP include the common difference, first term, last term, and number of terms.

Q: How do I find the common difference in an Arithmetic Progression?

A: To find the common difference, subtract the first term from the second term.

Q: How do I find the first term in an Arithmetic Progression?

A: To find the first term, use the formula: a = a + (n - 1)d, where a is the first term, n is the number of terms, and d is the common difference.
