$$\sum_{i=2}^{∞} \frac{1}{i^3-i}$$

yeah that above (Hopefully you can see)

So I know that i^3 - i is factored as i(i+1)(i-1) and just fiddled around trying to find sensible patterns

(Is it 1/4? I got that after like some random nonsense lol)

Thanks

(Also can this just be answered (or not) but NOT end in a thread of people attacking eachother like my previous question? :] )

As follows:

The third line above should have "Let j = i+1".
