1. The problem involves understanding the expression $n + 1$. 2. This is a simple algebraic expression where $n$ is a variable and $1$ is a constant. 3. The expression means to add 1 to the value of $n$. 4. For example, if $n = 3$, then $n + 1 = 3 + 1 = 4$. 5. This expression is often used to represent the next integer after $n$ or to increment a value by 1. 6. There are no further simplifications possible for $n + 1$ as it is already in its simplest form. 7. Therefore, the final answer is simply $n + 1$.
