Find out the next two numbers in the series.

1216 , 1442 , 2884 , 56168, _ ,_ ,............

Answer

There is a small issue with the question. The first number doesn't fit to the pattern exactly.  

Anyways this is the pattern I had on mind.

12 16 ,   1442 ,    2884 ,   56168,   _   ,  _  ,............

14 = (12 +16)/2    42  =14 * 3

28 = (14+42)/2     84  =28 * 3

56= (28+84)/2      168= 56* 3

14 , 28 , 56 ,112 ,224 ,.......................

42 , 84 ,168 ,336,672,.....................

Next two numbers  112336 , 224672 

1216 , 1442 , 2884 , 56168,  112336 ,224672 ,............
