In for example the (one of many, new) three combinatoric sequences offset=1
1,2,5,9,17,39,95,217,473,1011,2147,4545,9601,20255,42703,90001,189657,399627,842019,1774105,3737937,7875575,16593247,34960681,73659385,
6,21,48,108,236,506,1080,2294,4854,10248,21614,45564,96028,202354,426376,898374,1892838,3988096,8402638,17703724,37300364,78588906,
3,11,28,63,138,298,642,1371,2908,6146,12970,27351,57654,121502,256026,539459,1136632,2394830,5045754,10631039,22398786,47192482,99430802,
one can find the same empirical formula
a(n)=4*a(n-1)-5*a(n-2)+2*a(n-3)+a(n-4)-2*a(n-5)+a(n-6) for n>=10
Are such formulas of interest? I don't see any like them offhand in EIS.
