Introduction

In this article, we will explore a simple recursive function and find the value of $f(6)$ given the initial condition $f(1) = 1$ and the recursive formula $f(n) = 2 f(n-1)$. This type of problem is a classic example of a linear recurrence relation, which is a fundamental concept in mathematics and computer science.

Understanding the Recursive Formula

The recursive formula $f(n) = 2 f(n-1)$ indicates that the value of $f(n)$ is twice the value of $f(n-1)$. This means that to find the value of $f(n)$, we need to know the value of $f(n-1)$, and to find the value of $f(n-1)$, we need to know the value of $f(n-2)$, and so on.

Finding the Value of $f(2)$

To find the value of $f(2)$, we can use the recursive formula $f(n) = 2 f(n-1)$. Since $f(1) = 1$, we have:

$f(2) = 2 f(1) = 2 \cdot 1 = 2$

Finding the Value of $f(3)$

To find the value of $f(3)$, we can use the recursive formula $f(n) = 2 f(n-1)$. Since $f(2) = 2$, we have:

$f(3) = 2 f(2) = 2 \cdot 2 = 4$

Finding the Value of $f(4)$

To find the value of $f(4)$, we can use the recursive formula $f(n) = 2 f(n-1)$. Since $f(3) = 4$, we have:

$f(4) = 2 f(3) = 2 \cdot 4 = 8$

Finding the Value of $f(5)$

To find the value of $f(5)$, we can use the recursive formula $f(n) = 2 f(n-1)$. Since $f(4) = 8$, we have:

$f(5) = 2 f(4) = 2 \cdot 8 = 16$

Finding the Value of $f(6)$

To find the value of $f(6)$, we can use the recursive formula $f(n) = 2 f(n-1)$. Since $f(5) = 16$, we have:

$f(6) = 2 f(5) = 2 \cdot 16 = 32$

Conclusion

In this article, we have found the value of $f(6)$ given the initial condition $f(1) = 1$ and the recursive formula $f(n) = 2 f(n-1)$. The value of $f(6)$ is 32. This type of problem is a classic example of a linear recurrence relation, which is a fundamental concept in mathematics and computer science.

Example Use Cases

Linear recurrence relations have many practical applications in computer science, such as:

• Dynamic programming: Linear recurrence relations are used to solve dynamic programming problems, which involve finding the optimal solution to a problem by breaking it down into smaller subproblems.
• Algorithms: Linear recurrence relations are used to analyze the time and space complexity of algorithms, which is crucial in computer science.
• Modeling: Linear recurrence relations are used to model real-world phenomena, such as population growth, financial markets, and epidemiology.

Introduction

In our previous article, we explored a simple recursive function and found the value of $f(6)$ given the initial condition $f(1) = 1$ and the recursive formula $f(n) = 2 f(n-1)$. In this article, we will answer some frequently asked questions about this problem.

Q: What is the recursive formula?

A: The recursive formula is $f(n) = 2 f(n-1)$. This means that the value of $f(n)$ is twice the value of $f(n-1)$.

Q: How do I find the value of $f(6)$?

A: To find the value of $f(6)$, you need to use the recursive formula $f(n) = 2 f(n-1)$ and start with the initial condition $f(1) = 1$. Then, you can find the value of $f(2)$, $f(3)$, $f(4)$, $f(5)$, and finally $f(6)$.

Q: Can I use a calculator to find the value of $f(6)$?

A: Yes, you can use a calculator to find the value of $f(6)$. Simply enter the recursive formula $f(n) = 2 f(n-1)$ and the initial condition $f(1) = 1$, and the calculator will give you the value of $f(6)$.

Q: Is there a faster way to find the value of $f(6)$?

A: Yes, there is a faster way to find the value of $f(6)$. You can use the formula for the nth term of a geometric sequence, which is $a_n = a_1 \cdot r^{n-1}$. In this case, $a_1 = 1$ and $r = 2$, so the formula becomes $f(n) = 1 \cdot 2^{n-1}$.

Q: How do I use the formula $f(n) = 1 \cdot 2^{n-1}$ to find the value of $f(6)$?

A: To use the formula $f(n) = 1 \cdot 2^{n-1}$ to find the value of $f(6)$, simply plug in $n = 6$ and calculate the result. You get $f(6) = 1 \cdot 2^{6-1} = 1 \cdot 2^5 = 32$.

Q: What is the significance of the value of $f(6)$?

A: The value of $f(6)$ is significant because it represents the 6th term of a geometric sequence with a common ratio of 2. This sequence has many practical applications in computer science, such as dynamic programming and algorithm analysis.

Q: Can I use the formula $f(n) = 1 \cdot 2^{n-1}$ to find the value of $f(n)$ for any positive integer $n$?

A: Yes, you can use the formula $f(n) = 1 \cdot 2^{n-1}$ to find the value of $f(n)$ for any positive integer $n$. Simply plug in the value of $n$ and calculate the result.

Conclusion

In this article, we have answered some frequently asked questions about the problem of finding the value of $f(6)$ given the initial condition $f(1) = 1$ and the recursive formula $f(n) = 2 f(n-1)$. We have also provided a formula for the nth term of a geometric sequence, which can be used to find the value of $f(n)$ for any positive integer $n$.
