Series Analysis Strategy

The goal is to count consonants that meet specific preceding and succeeding letter conditions within the given series.

Defining Vowels and Consonants

• Vowels: A, E, I, O, U
• Consonants: All other letters (B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W, X, Y, Z).

Applying the Condition: Consonant-Consonant-Vowel Pattern

We need to find consonants (let's call the target consonant 'C1') where the letter immediately before it ('C0') is also a consonant, and the letter immediately after it ('V0') is a vowel. The pattern to look for is C0 C1 V0.

Step-by-Step Examination

Let's examine the series from left to right: \(N E F M L C L T X X R X D G J A M Q F T Q\)

We check triplets of letters:

• \(N E F\): E is a vowel.
• \(E F M\): F follows a vowel E.
• \(F M L\): L is a consonant, follows consonant M, but precedes consonant F. (M L F pattern - fails: L is not followed by vowel).
• \(M L C\): C is a consonant, follows consonant L, but precedes consonant L. (L C L pattern - fails: C is not followed by vowel).
• \(L C L\): L is a consonant, follows consonant C, but precedes consonant L. (C L L pattern - fails: L is not followed by vowel).
• \(C L T\): T is a consonant, follows consonant L, but precedes consonant T. (L T T pattern - fails: T is not followed by vowel).
• \(L T X\): X is a consonant, follows consonant T, but precedes consonant X. (T X X pattern - fails: X is not followed by vowel).
• \(T X X\): X is a consonant, follows consonant X, but precedes consonant X. (X X X pattern - fails: X is not followed by vowel).
• \(X X R\): R is a consonant, follows consonant X, but precedes consonant R. (X R R pattern - fails: R is not followed by vowel).
• \(X R X\): X is a consonant, follows consonant R, but precedes consonant X. (R X X pattern - fails: X is not followed by vowel).
• \(R X D\): D is a consonant, follows consonant X, but precedes consonant D. (X D D pattern - fails: D is not followed by vowel).
• \(X D G\): G is a consonant, follows consonant D, but precedes consonant G. (D G G pattern - fails: G is not followed by vowel).
• \(D G J\): J is a consonant, follows consonant G, but precedes consonant J. (G J J pattern - fails: J is not followed by vowel).
• \(G J A\): J is a consonant. It is preceded by consonant G and followed by vowel A. This matches the condition (C0 C1 V0 pattern).
• \(J A M\): A is a vowel.
• \(A M Q\): M is a consonant, but follows a vowel A.
• \(M Q F\): F is a consonant, follows consonant Q, but precedes consonant F. (Q F F pattern - fails: F is not followed by vowel).
• \(Q F T\): T is a consonant, follows consonant F, but precedes consonant T. (F T T pattern - fails: T is not followed by vowel).
• \(F T Q\): Q is a consonant, follows consonant T, but precedes consonant Q. (T Q Q pattern - fails: Q is not followed by vowel).

Final Count and Conclusion

Only one letter, 'J', satisfies the condition of being a consonant immediately preceded by a consonant and immediately followed by a vowel.

Therefore, there is One such consonant.
