%N Least prime in arithmetic progression of consecutive primes 6^n+k, 6^n+k+g, 6^n+k+2*g with smallest k.
%C No solution for n = 1, so sequence starts at n = 2.
%C The primes are probable primes for n > 23.
%F a(n) = 6^n + A233546(n).
%e a(2) = 6^2 + A233546(2) = 36 + 11 = 47.
%Y Cf. A233546 (values of k), A233550 (values of g), A233742 (= g/6).
