The number which best completes the sequence below is 20 5 30 6 42 7
56 (just the next number, not the number that completes the sequence)
Not sure about completes becasue the series look like it should be infinite. The best continuation is 28, 32, ...
The next number is 7 X 8 is 56.

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, ...
