Pretty difficult function

Here is the function:

Code:

---

x(n) = 61x(n-1) + i + 32

---

Basically, it starts at x=0, it multiplies x by 61 and adds 32 and i.

Assume i is 12,

1st time: x=44
2nd time: x=2728


I need to get x(n-1) starting from the last number

So for example if I supply x=2728, the answer will give me a reduced value of (44).

What exactly is your question, because
x(n) = 61x(n-1) + i + 32



i.e. x_n = 2728, i=12
