There is potentially a very powerful concept available here, where we will be able to write a functional form of sorts for expressions such as $n \;\mod\;m$.
It is becoming increasingly clear that there may be two sequences involved in describing certain hard to fit members. Then the input series is actually of the form \begin{equation}
C_0,a_1,b_1,a_2,b_2,a_3,b_3...
\end{equation}
where $C_0$ is just a leading coefficient, and then the two sequences $a$ and $b$ progress with their description. Then many sequences will start with $C_0=1$, if they start with $1$.
Then sequence $A134425$ actually has two input sequences \begin{equation}
a=5,13/5,29/13,61/29,125/61...\\
b=2/5,10/13,26/29,58/61...\\
\end{equation}
We then see that for the sequence \begin{equation}
t=1,5,13,29,61,125...\\
\end{equation}
we can define \begin{equation}
a_i = \frac{t_{i+1}}{t_{i}}
\end{equation}
it then follows that \begin{equation}
b_{i}=\frac{2}{a_i}
\end{equation}
