The limit of a Nasty Summation
I'm trying to evaluate the limit as h approachs 0 of the sum from k = 0 to n of:
$\frac{1}{h^n}(-1)^{k+n}\binom{n}{k}\frac{1}{(x+kh)^2-2(x+kh)+17}$
If it helps, it's the limit definition of the nth ...

Reduction of $_3\text F_2(a,a,1-b;a+1,a+1;x)$ with the hypergeometric function
A derivative of the incomplete beta function $\text B_x(a,b)$ uses hypergeometric $_3\text F_2$
$$\frac{d\text B_x(a,b)}{da}=\ln(x)\text B_x(a,b)-\frac{x^a}{a^2}\,_3\text F_2(a,a,1-b;a+1,a+1;x)$$
Now ...
