I had done some work on this in the past

1) How do I submit the two terms found 6071, 218431?
2) Is there an efficient sieve for these forms?
3) Would these sequences be finite?
1) get an OEIS account, ( or use somebody who has one) to edit the sequence.
2) modular remainders are inefficient but give that if a(n-1) is 2 mod 3, k is odd, if a(n-1) is 1 mod 3,k is even.( Oops math for the related sequence)
3) no clue.
