The first letter is B, then next is C. C skip one its becomes E. After E, again skip one, it becomes G. Hence , skipping of letter fails. So, convert it into a Number Series.

B = 2, C = 3, E = 5, G = 7, K = 11

If the numbers are assigned, the series will become series of prime numbers. The next prime number is 13 and the corresponding letter is M.
