%N Primes p such that 5 is the largest of all prime factors of the numbers between p and the next prime (cf. A052248).
%C The sequence consists of 7 and the lesser of twin primes q (A001359) such that q+1 is 5smooth (A051037) but not 3smooth (A003586, A080193).
%e 7 is a term since 8 = 2^3, 9 = 3^3, 10 = 2*5 are the numbers between 7 and the next prime 11; 149 is a term since 150 = 2*3*5^2 is the only number between 149 and the next prime 151.
