Find out the next two numbers in the series.

3457, 6918 ,13832 , 27668 , _ ,_ ,............

Answer

3457, 6918 ,13832 , 27668 ,  _  , _  ,............

6918    = (3457   +2)  * 2

13832  = (6918   -2)   * 2

27668  = (13832 +2)  * 2

Next two numbers 

(27668 -2 )  * 2 = 55332

(55332+2)  * 2  = 110668 

3457, 6918 ,13832 , 27668 ,  55332 , 110668   ,............
