It's not clear what you're supposed to do, but I would guess that you're asked to find a certain term in the sequence.

Given

$\begin{cases}t_1=9\\t_n=t_{n-1}-4&\text{for }n1\end{cases}$

you can do that by solving for t_n

explicitly.

$t_n=t_{n-1}-4=t_{n-2}-2\times4=t_{n-3}-3\times4=\cdots=t_1-(n-1)\times4$

So the explicit formula for the

th term is

t_n=9-4(n-1)=13-4n
