This site is supported by donations to The OEIS Foundation.

 Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing. Other ways to donate

 OFFSET 0,3 COMMENTS Binomial transform of Jacobsthal(n)(1-(-1)^n)/2. Starting with "1" = A001045 convolved with A025192: i.e (1, 2, 6, 16, 46,...) = (1, 1, 3, 5, 11,...) * (1, 2, 6, 18, 54,...). - Gary W. Adamson, May 10 2013 LINKS Index entries for linear recurrences with constant coefficients, signature (4,-1,-6). FORMULA G.f.: x(1-2x-x^2)/((1+x)(1-2x)(1-3x)) a(n) = 3^n/6 - (-1)^n/6 + 2^n/6 - 0^n/6.
