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, ...

If you want to take 25% of off 140. Multiply 140 by .4 to find 25% (this is 35). Then subtract 35 from 140: 140-35 = 105. You could also subtract 25 from 100: 100-25 =75. Then multiply 140 by .75 and you will get 105.
15, 21, 25, 35, 75, 105, 175, 525
The factor pairs of 525 are: (1, 525), (3, 175), (5, 105), (7, 75), (15, 35).
105/75=1.4 1.4 X 100=140% 140%
