The equation in the image is:

$A_n = \frac{n + 1}{n^2}, \quad n > 0$

This is a sequence formula where $A_n$ depends on $n$, and the constraint is that $n$ must be greater than 0. The formula gives the general term $A_n$ of the sequence as the quotient of $n + 1$ and $n^2$.

Would you like a detailed explanation of how this sequence behaves, or do you have specific questions about it?

Here are some related questions you might want to explore:

1. How does $A_n$ behave as $n$ increases (e.g., does it converge)?
2. What is the limit of $A_n$ as $n \to \infty$?
3. How can you find the sum of the sequence $A_n$ for specific values of $n$?
4. Can you find the maximum or minimum of $A_n$ for specific intervals of $n$?
5. How can this formula be applied to solve real-world problems?

Tip: When dealing with sequences like this one, it's often helpful to analyze their limit behavior to understand their long-term trend.
