Table of n, a(n) for n=1..49.

FORMULA

a(2*n-1) = A000960(3*n-2), where A000960 is Flavius Josephus's sieve.

EXAMPLE

a(1)=1: 1;

a(2)=5: 2->5;

a(3)=13: 3->10->13;

a(4)=25: 4->15->22->25;

a(5)=39: 5->20->30->36->39;

a(6)=61: 6->25->40->51->58->61;

a(7)=79: 7->30->45->60->69->76->79;

a(8)=103: 8->35->54->70->84->93->100->103;

a(9)=133: 9->40->63->84->100->112->123->130->133;

a(10)=169: 10->45->72->98->120->135->148->159->166->169.

MATHEMATICA

f[n_] := Fold[#2*Ceiling[#1/#2 + 3] &, n, Reverse@ Range[n - 1]]; Array[f, 49]

PROG

(PARI) a(n)=local(A=n, D); for(i=1, n-1, D=n-i; A=D*ceil(A/D+3)); A
