Introduction

Sequences are an essential concept in mathematics, used to describe a series of numbers that follow a specific pattern or rule. In this article, we will explore two sequences, $f(n)$ and $g(n)$, and evaluate their values at specific points. We will also compare the values of these sequences to determine the correct statement among the given options.

Sequence $f(n)$

The sequence $f(n)$ is defined as $f(n) = 2^{(n-1)} - 1$. This sequence represents a geometric progression with a common ratio of 2. To evaluate the value of $f(n)$ at a specific point, we can substitute the value of $n$ into the formula.

Calculating $f(5)$

To calculate the value of $f(5)$, we substitute $n = 5$ into the formula:

$$f(5) = 2^{(5-1)} - 1$$

$$f(5) = 2^4 - 1$$

$$f(5) = 16 - 1$$

$$f(5) = 15$$

Sequence $g(n)$

The sequence $g(n)$ is defined as $g(n) = 3n + 6$. This sequence represents a linear progression with a slope of 3. To evaluate the value of $g(n)$ at a specific point, we can substitute the value of $n$ into the formula.

Calculating $g(3)$

To calculate the value of $g(3)$, we substitute $n = 3$ into the formula:

$$g(3) = 3(3) + 6$$

$$g(3) = 9 + 6$$

$$g(3) = 15$$

Calculating $g(6)$

To calculate the value of $g(6)$, we substitute $n = 6$ into the formula:

$$g(6) = 3(6) + 6$$

$$g(6) = 18 + 6$$

$$g(6) = 24$$

Comparing the Values

Now that we have calculated the values of $f(5)$, $g(3)$, and $g(6)$, we can compare them to determine the correct statement among the given options.

• Option A: $f(5) \ \textless \ g(3)$
• Option B: $g(6) \ \textgreater \ f(5)$

From our calculations, we can see that:

• $f(5) = 15$
• $g(3) = 15$
• $g(6) = 24$

Since $f(5) = g(3)$, option A is incorrect. However, option B is correct because $g(6) > f(5)$.

Conclusion

In conclusion, we have evaluated the sequences $f(n)$ and $g(n)$ and compared their values at specific points. We have determined that the correct statement among the given options is option B: $g(6) \ \textgreater \ f(5)$. This result highlights the importance of carefully evaluating and comparing the values of sequences to make accurate conclusions.

Q&A: Sequences and Their Applications

Introduction

In our previous article, we explored the sequences $f(n)$ and $g(n)$ and compared their values at specific points. In this article, we will answer some frequently asked questions about sequences and their applications in mathematics and computer science.

Q: What is a sequence?

A sequence is a series of numbers that follow a specific pattern or rule. Sequences can be used to model real-world phenomena, such as population growth, financial transactions, and physical systems.

Q: What are the different types of sequences?

There are several types of sequences, including:

• Arithmetic sequences: These sequences have a common difference between each term.
• Geometric sequences: These sequences have a common ratio between each term.
• Harmonic sequences: These sequences have a common difference between the reciprocals of each term.
• Fibonacci sequences: These sequences are a series of numbers in which each number is the sum of the two preceding numbers.

Q: How are sequences used in mathematics?

Sequences are used in mathematics to:

• Model real-world phenomena: Sequences can be used to model population growth, financial transactions, and physical systems.
• Solve equations: Sequences can be used to solve equations and inequalities.
• Analyze data: Sequences can be used to analyze data and identify patterns.

Q: How are sequences used in computer science?

Sequences are used in computer science to:

• Model algorithms: Sequences can be used to model algorithms and analyze their performance.
• Analyze data: Sequences can be used to analyze data and identify patterns.
• Develop software: Sequences can be used to develop software and model real-world phenomena.

Q: What are some examples of sequences in real life?

Some examples of sequences in real life include:

• Population growth: The population of a city or country can be modeled using a sequence.
• Financial transactions: The number of transactions in a bank account can be modeled using a sequence.
• Physical systems: The motion of a physical system, such as a pendulum or a spring, can be modeled using a sequence.

Q: How can I learn more about sequences?

There are several resources available to learn more about sequences, including:
