f(n)=(1/2)f(n+1)+(1/2)f(n-1)-1(adsbygoogle = window.adsbygoogle || []).push({});

I got f(n)=n^2.

I can not find anymore solution except this.

I just wonder there are some more solutions about this problem or not.

I think there are more, but I don't know how to get to them.

I wanna hear your opinion.

Thanks
