The given sequence is an arithmetic sequence where each term increases by 1.

To express the nth term of the sequence, we can start with the first term, which is 42. Since each subsequent term increases by 1, the nth term can be expressed as:

\[ a_n = 42 + (n - 1) \cdot 1 \]

Simplifying this expression gives us:

\[ a_n = 42 + n - 1 \]
\[ a_n = n + 41 \]

So, the expression for the nth term is:

\[ a_n = n + 41 \]
