Perhaps there are 3 interleaved series
  • the second number is 3 times the first
  • the third number is 1/2 the second
  • the fourth number is 1 more than the third.
It appears the triples are
  10 30 15
  16 48 24
  25 75 37.5
After that, the series degenerates into mixed numbers with increasingly complicated fractions.
According to the above definition, the next number is 75.
