%N One sixth of gap g between 3 consecutive primes for the smallest k such that 6^n+k, 6^n+k+g, 6^n+k+2*g are consecutive primes in arithmetic progression
%C g is a multiple of 6 as otherwise 6^n+k, 6^n+k+g, or 6^n+k+2*g is divisible by 2 or 3.
%C Sequence starts at n=2 as no solution for n=1.
%C k=A233546(n).
%F a(n) = A233550(n)/6.
%Y Cf. A233546, A233550.
