Solution
The correct option is C 4032
A careful scrutiny of the given series reveals that second term is 2 times the first, the third term is 4 times the second and fourth term is 3 times the third. The same pattern is being followed by the remaining terms of the series. Therefore, 2688 should be replaced by 4032. Hence, alternative (c) is the correct alternative.
