Introduction

In mathematics, patterns are an essential concept that helps us understand and describe the world around us. A pattern is a sequence of numbers, shapes, or objects that follow a specific rule or rule set. In this article, we will explore a given pattern and derive an algebraic equation that represents it.

The Pattern

The given pattern is represented in a table with four terms, each with a corresponding value.

Term number (t)	1	2	3	4
Term value (N)	8	4	0	-4

Algebraic Equation Representation

To derive an algebraic equation that represents the pattern, we need to identify the relationship between the term number (t) and the term value (N). Let's examine the given values:

For t = 1, N = 8
For t = 2, N = 4
For t = 3, N = 0
For t = 4, N = -4

We can observe that the term value (N) is decreasing by 4 each time the term number (t) increases by 1. This suggests a linear relationship between t and N.

Deriving the Algebraic Equation

Let's assume the algebraic equation that represents the pattern is of the form:

N = at + b

where a and b are constants.

We can use the given values to set up a system of equations:

For t = 1, N = 8: 8 = a(1) + b
For t = 2, N = 4: 4 = a(2) + b
For t = 3, N = 0: 0 = a(3) + b
For t = 4, N = -4: -4 = a(4) + b

Solving this system of equations, we get:

a = -4 b = 12

Therefore, the algebraic equation that represents the pattern is:

N = -4t + 12

Verification

Let's verify that the derived algebraic equation represents the pattern by plugging in the term numbers and checking if the corresponding term values match.

Term number (t)	Calculated N	Given N
1	-4(1) + 12 = 8	8
2	-4(2) + 12 = 4	4
3	-4(3) + 12 = 0	0
4	-4(4) + 12 = -4	-4

The calculated term values match the given term values, verifying that the derived algebraic equation represents the pattern.

Conclusion

Introduction

In our previous article, we explored a given pattern and derived an algebraic equation that represents it. In this article, we will answer some frequently asked questions (FAQs) related to the pattern and algebraic equation representation.

Q: What is the significance of the algebraic equation N = -4t + 12?

A: The algebraic equation N = -4t + 12 represents the pattern in a mathematical form. It shows the relationship between the term number (t) and the term value (N). This equation can be used to predict the next term value in the pattern.

Q: How did you derive the algebraic equation N = -4t + 12?

A: We derived the algebraic equation by identifying the relationship between the term number (t) and the term value (N). We observed that the term value (N) is decreasing by 4 each time the term number (t) increases by 1. This suggests a linear relationship between t and N. We then set up a system of equations using the given values and solved for the constants a and b.

Q: What is the difference between the term number (t) and the term value (N)?

A: The term number (t) is the position of the term in the pattern, while the term value (N) is the actual value of the term. In the given pattern, the term number (t) starts from 1 and increases by 1 for each subsequent term, while the term value (N) starts from 8 and decreases by 4 for each subsequent term.

Q: Can you explain the concept of linear relationship between t and N?

A: A linear relationship between t and N means that the term value (N) changes at a constant rate with respect to the term number (t). In this case, the term value (N) decreases by 4 for each increase in the term number (t) by 1.

Q: How can I use the algebraic equation N = -4t + 12 to predict the next term value in the pattern?

A: To predict the next term value in the pattern, simply plug in the next term number (t) into the algebraic equation N = -4t + 12. For example, if we want to find the next term value after t = 4, we can plug in t = 5 into the equation:

N = -4(5) + 12 N = -20 + 12 N = -8

Therefore, the next term value in the pattern is -8.

Q: Can I use the algebraic equation N = -4t + 12 to find the term value for any term number (t)?

A: Yes, you can use the algebraic equation N = -4t + 12 to find the term value for any term number (t). Simply plug in the term number (t) into the equation and solve for N.

Q: What are some real-world applications of algebraic equation representation?

A: Algebraic equation representation has many real-world applications, including:

Modeling population growth and decline
Predicting stock prices and market trends
Analyzing data and identifying patterns
Solving optimization problems and making decisions
