First Series could be A006450 or A175247 (Primes with noncomposite subscripts.)

In spite of the type of the series, the answer becomes

67.

And the second one A007570 = $F(F(n))$ where F is a Fibonacci number.

so the answer becomes

10946

And there is no relation that I have found between these.
