a(n) is the smallest prime q such that, for the previous prime p and the following prime r, the fraction (r-q)/(q-p) has denominator n in lowest terms. A179234

a(n) is the smallest prime q such that (q-p)/(r-q) = n, where p<q<r are consecutive primes (or 0 if none exist). A179256

Generalized Pellian with second term equal to 7. A48694

Middle q of three consecutive primes p,q,r, such that one adjacent prime is near, the other is far and the ratio of the differences (whichever of (r-q)/(q-p) or (q-p)/(r-q) is greater than 1) sets a record. A84105

a(n) = 6·a(n-1) - a(n-2) for n > 1; a(0) = 1, a(1) = 15. A164541
