**Mathematical Series Ratio Problem:**

*What is the ratio of the \((n + 1)^\text{th}\) term to the \(n^\text{th}\) term of the series when \(n\) is greater than 0?*

In this exercise, you are tasked with finding the ratio of consecutive terms in a numerical series, specifically the \((n + 1)^\text{th}\) term compared to the \(n^\text{th}\) term, given that \(n\) is a positive integer. This type of problem is essential in understanding the behavior of sequences and series in mathematics, often applied in calculus and algebra. 

To solve this, you'd typically need the formula or definition of the series given, which allows you to compute each term's value and thereby determine their ratio. If such details are missing, consider researching common series types like arithmetic or geometric sequences for a deeper analysis.

**Title:** Visualizing Taylor Polynomials for the Function \( f(x) = \log(x + 5) \)

**Introduction:**
Explore how Taylor polynomials approximate the function \( f(x) = \log(x + 5) \) at \( x_0 = 0 \).

**Graph Details:**

- **Function Graph (Black):** Represents the function \( f(x) = \log(x + 5) \).
- **Taylor Polynomial of Degree 0 (Blue):** Constant approximation, tangent to the function at \( x = 0 \).
- **Taylor Polynomial of Degree 1 (Orange):** Linear approximation, better fit near \( x = 0 \).
- **Taylor Polynomial of Degree 2 (Green):** Quadratic approximation, capturing more curvature.
- **Taylor Polynomial of Degree 3 (Red):** Cubic approximation, improving accuracy.
- **Taylor Polynomial of Degree 4 (Purple):** Further refinement with a quartic polynomial.
- **Taylor Polynomial of Degree 5 (Pink):** Quintic approximation, closely follows the function.
- **Taylor Polynomial of Degree 6 (Cyan):** Additional accuracy, especially near \( x = 0 \).

**Instructions:**
- Construct the Taylor series for \( f \) at \( x_0 = 0 \).
- \( f^{(n)} \) denotes the \( n \)-th derivative of \( f \), where \( f^{(0)} \) is \( f \) itself.
- Use `*` for all multiplications for clarity.
- Avoid using "!" for factorials; instead, express as products, e.g., \( 4*3*2 \) for \( 4! \).

**Note:**
A row will be marked incorrect if any element is wrong. Accuracy is key when entering mathematical expressions.
