The numerical value of each term represents a musical scale based on an equal division of the octave. 19, for example, signifies the scale which is formed by dividing the octave into 19 equal parts. %F A060233 Recurrence: The next term equals the current term plus one or more of the previous terms: a(n+1) = a(n) + a(n-x)... + a(n-y)... + a(n-z), etc. %e A060233 6 = 4 + the previous term 2. Again, 48545 = 46625 + the previous terms (1578 + 270 + 72). %Y A060233 A054540, A060525, A060526, A060527, A060528, A060529, A001149, A000045. %K A060233 nonn %O A060233 1,2 %A A060233 Mark William Rankin (MarkRankin95511(AT)Yahoo.com), Apr 14 2001
