34

This number is a composite.

Of all the primes produced by 34n + n - (n + 1)² for n = 1 - 34, only one is an isolated prime. Although the twin primes produced are not distinct it is interesting to note that there are two twin primes in the first three n values, three from 5, i.e., 5/8, 8/13, 13/21 and twenty-one twin primes from thirty-four n values, giving a ratio of primes produced exactly equal to the Golden Ratio throughout the sequence.
