Came across the fact that \[ \frac{1}{96} = \sum_{k=1}^{\infty} \frac{k^2}{(k+1)(k+2)(k+3)(k+4)(k+5)} \], without any references.

How do I go about proving that? I hope the answer doesn't involve the Riemann ζ function.

@jsiehler the first two terms are 1/720 and 4/2520.

jsiehler@jsiehler@mathstodon.xyz@christianp Unless my early-morning eyes are reading something wrong, the second partial sum is already 1/120 + 4/360 = 7/360 > 1/96.
