Hello,

I'm not sure if this is the right forum -- I'm not a student so I've not arrived at this problem in a textbook context.

I want to solve an equation of the form:

(a^n)b-(a^n-1)c-(a^n-2)c-...-ac-c=0

where a, b, and c are constants and n is the unknown to be found.

Any pointers -- whether on the problem or on where to go to pose it again -- would be appreciated.

Regards,

Isolde.
