%U 38

%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.

%K nonn

%O 2,5
