Find the missing term in the series:C, X, M, N, J, ?

The given series is C, X, M, N, J, ?

The pattern in the series is based on the positions of the letters in the English alphabet.

C is the 3rd letter, X is the 24th letter, M is the 13th letter, N is the 14th letter, and J is the 10th letter.

If we look at the differences between these positions, we get:

24 - 3 = 21 13 - 24 = -11 14 - 13 = 1 ? - 14 = ?

We can see that the differences are decreasing by 11 each time (21, -11, 1). So, the next difference should be -11.

Therefore, the position of the missing letter should be 14 - 11 = 3.

The 3rd letter of the alphabet is C.

So, the missing term in the series is C.
