Maybe a wrong answer, but possibly a valid solution! Two "split" series: (1) 24, 210, 1716 , 4542, ...., and (2) 60, 504, 2730, 6738, ... if we consider two polynomial series:

1st: y = 660x^2 - 1794x + 1158

2nd: y = 891x^2 - 2229x +1398

Far fetched?

The series

33-3=24

43-4=60 .

63-6=210

83-8=504

123-12=1716

143-14=2730

243-24=13800

223-22=10626

4,8,14,22-series--4=12+3        8=22+4   14=32+5       22=42+6

3,6,12,24----with common ratio 2

The series

1st series

4,8,14,22-series 4=12+3        8=22+4   14=32+5      22=42+6

2nd series

3,6,12,24----with common ratio 2
