Gauss's Forward Formula


\begin{displaymath}
f_p=f_0+p\delta_{1/2}+G_2\delta_0^2+G_3\delta_{1/2}^3+G_4\delta_0^4+G_5\delta_{1/2}^5+\ldots,
\end{displaymath}

for $p\in[0,1]$, where $\delta$ is the Central Difference and
$\displaystyle G_{2n}$ $\textstyle =$ $\displaystyle {p+n-1\choose 2n}$  
$\displaystyle G_{2n+1}$ $\textstyle =$ $\displaystyle {p+n\choose 2n+1},$  

where ${n\choose k}$ is a Binomial Coefficient.
