The next one is

$\frac{1254027132096}{886731088897}$.

  • $\begingroup$ I got the same answer. For those who have a hard time understanding the link posted by @WhatsUp, the next denominator in the pattern seems to be the denominator^2 times 2 minus 1. And for the numerator, you multiply the denominator by ~1.41421356237 to calculate. $\endgroup$
