0 rocdocmac Posted August 18, 2016 Report Share Posted August 18, 2016 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?
