The sequence given is:

\[ 1, 2, 3, 4, 5, \dots \]

This is an arithmetic sequence where each term increases by 1. To find a general expression for the \(n\)-th term \(t_n\) of this sequence, we can use the formula for the \(n\)-th term of an arithmetic sequence:

\[
t_n = a + (n-1) \cdot d
\]

where:
- \(a\) is the first term of the sequence,
- \(d\) is the common difference between consecutive terms,
- \(n\) is the term number.

For this sequence:
- The first term \(a = 1\),
- The common difference \(d = 1\).

Substituting into the formula:

\[
t_n = 1 + (n-1) \cdot 1
\]
\[
t_n = n
\]

So, the general expression for the \(n\)-th term is simply:

\[
t_n = n
\]

This means that the \(n\)-th term of the sequence is just \(n\) itself.
