This would imply a(3)=37. (7,19,31, for example, is a progression ending with 31.) %Y A216539 A216495 conjectures a(3). %Y A216539 A094383 conjectures a(4). %Y A216539 A216497 conjectures a(5). %Y A216539 A216498 conjectures a(6). %Y A216539 A216468 conjectures a(7). %Y A216539 A216590 conjectures a(8). %Y A216539 Cf.
