Recursive Function.

Dear All,

I have a recursive function I am unable to solve.  Does anybody have any ideas as to what steps can be taken?

Here it is:



where

is a constant, and n represents any number of iterations.


Thanks for your help.

Best,

Re: Recursive Function.

Sorry, i forgot to mention that A is a constant as well.

Re: Recursive Function.

If

= 210 and A = 210, can you show me
how it starts off?  210 is divisble by lots of small numbers.

Re: Recursive Function.

Sorry, the equation had a slight error:

the initial value of P is know. I will call this

: here is the final equation.. please note the change of "-" to "+" sorry:

As an example:


so, if you solve for the case where n = 2:



so,


Then, you have the following equation for P_2:

plugging in the initial

, and the previously solved
, you get an answer for
of:


Thanks for your help.

If n =3, then the you would have to change the value of n in the equations, and as a result the values of P0, P1, and P3 would change.
Let me know if there are any questions, or if the previous example is not clear.


Thanks again.

Best,
Prad
