Is that simplified? I'm just going off of this image: http://ajennings.net/blog/images/formula.png

me too, the pattern to me is odds on the numerator and evens in the denominator, and the second fraction goes 1/3, 1/5, 1/7, 1/9...

i think we're saying the same thing i misunderstood your comment. 1357/2468 is the first fraction of the NEXT line that isnt in the image

Aha, yes, I edited my post now to say 4th line not 4th step. Leave it to HN to get an off-by-one error :)
