comment Derivation of finite difference schemes for a boundary value problem.
Okay thanks. It does not specifically ask for a first order central difference, it just asks for "the central difference scheme for computing the numerical solution of the equation". Do you know what this means, exactly?

I see, thank you. It has been a long time since I have worked with geometric series.

So you are essentially just left with $1 - x^{100}/(1 + x)$? That is very convenient :)

Cannot believe I messed up this basic stuff. Thanks.
