Is it enough to find the successor term of $\frac{14}{17}$ in fairy sequence $f_{17}$?

By the definition of Farey sequence, yes. But that too involves manual search for a primitive solution of a linear diophantine equation.

I used Continued Fraction. And got $\frac{11}{6}$. Is it one from the right ways?
