It seems like part of your question got cut off, especially the recursive formula for the sequence. You provided the initial term $a_1 = 59$, but the recursive formula is missing from the message.

Could you please clarify or provide the full recursive formula for $a_n$? The recursive formula should express $a_n$ in terms of the previous term(s), such as:

$a_n = f(a_{n-1}) \quad \text{(or something similar)}.$

Once you provide that, I'll be able to find the explicit formula for the sequence.
