r^n - n(5m(r-1)) > H/D(r-1)+1 i'm half way through completing this equation. i have a sequence D1 to Dn. r represents the common ratio Dn/Dn+1. H and m are constants. can anyone isolate n into the subject of this equation? thanks guys, please let me know if it just isnt possible, but as far as im concerned there is only one unknown so it should be, my mathimatics is not great but if this ends up as a logarithmic equation i can deal with that, thanks again.
