“…It is well-known that the Jacobsthal sequence (sequence A001045 in [5]) {Jn} is defined recursively by the equation, for n ≥ 0 Jn+2 = Jn+1 + 2Jn in which J0 = 0 and J1 = 1. Then Jacobsthal sequence (second order Jacobsthal sequence) is 0, 1, 1, 3,5,11,21,43,85,171,341,683,1365,2731, 5461, 10923, ... This sequence has been studied by many authors and more detail can be found in the extensive literature dedicated to these sequences, see for example, [6,7,8,9,10,11,12,13,14,15,16,17,18].…”
