This is an OK thing to do here, indeed, users are encouraged to post answers to their own questions, when they learn something that enables them to answer their questions. | |
| Jun 25 at 16:11 | comment | added | Abou Zeineb | Thank you @GerryMyerson I find the sequence $a_n$ for the G.f.: 1/((1-x)*(1-x^3)*(1-x^4)). 1, 1, 1, 2, 3, 3, 4, 5, 6, 7, 8, 9, 11, 12, 13, 15, 17, 18, 20, 22, 24, 26, 28, 30, 33, 35, 37, 40, 43, 45, 48, 51, 54, 57, 60, 63, 67, 70, 73, 77, 81, 84, 88, 92, 96, 100, 104, 108, 113, 117, 121, 126, 131, 135, 140, 145, 150, 155, 160, 165, 171, 176, 181, 187, 193, 198… Then $a(10)=8$ And the formula $a(n) = floor(n^2/24+n/3+1) $ I can verify in this formula $a(n) = floor(100/24+10/3+1)=4+3+1=8 $ | |
