You'll need to decide where the spaces are in your number sequence before this could be answered. Is it 3 9 4 5 2 5 2 0 2 1 4 4 1 or 39 45 25 20 21 44 1 or some other interpretation. Your current sequence could be just one number 3,945,252,021,441
Not sure about "completes" because the sequence continues. The next number is 20 and you can verify that by fitting the following cubic equation: u(n) = 5*(-n3 + 36n2 - 257n + 558)/12 for n = 1, 2, 3, 4, ...
next in the sequence: 10,20,30,20
