Does anyone know how to calculate the exact value of this continued fraction [2;3,5,7,11,13,17,...] ?

My guess is that it can't be simplified.

Wild guess: log(exp(1)+1)+1

You can using this formula S=a/1r where S=sum of terms to infity a=first term r=common ratio

There isn't a common ratio in this case.
