If we remove all the alternate 2 we get 3,3,4,3,3,5,3,3,4,3,3,5,3,3,4,3,3,5, ie a repeating sequence of 3,3,4,3,3,5. Ans = 2,3,2,3,2,4,2,3,2,3,2,5 * 4, 4, 341, 6, 4, 4, 6, 6, 4, 4, 6, 10, 4, 4, 14, 6, 4, 4, 6, 6, 4, 4, 6, 22, 4, 4, 9, 6, ? Clearly if we remove double sequences of 4 we get 341 ,6 ,6 ,6 ,6 ,10, 14, 6, 6 ,6 ,6 , 22 , 9 , 6 If we remove sequences of 4 6's we get 341,10,14,22,9, which do not forms any sequence so,,,,,this question seems to be wrong......
