The generalized Fibonacci sequence seems to generate at least one prime
regardless of the values assigned to Fib(1), Fib(2), *unless* Fib(1) and
Fib(2) are even. Then there is never an odd number, and never a chance for a
prime after Fib(2) (though Fib(1) or Fib(2) may be =2, but that seems
trivial).
I tried it with composite odd numbers, such as 15,77, which happen to be
coprime. The first 3 primes generated are Fib(7)=691, Fib(14)=20101, and
Fib(28)=16945081.
