Letter Sequence Pattern Analysis

The question asks to identify the next letter in the sequence: Z, X, U, Q, ?

Determining the Alphabetical Step

We can find the pattern by looking at the numerical positions of the letters in the alphabet (A=1, B=2, ..., Z=26):

  • Z is the 26th letter.
  • X is the 24th letter.
  • U is the 21st letter.
  • Q is the 17th letter.

Now, let's calculate the difference in positions between consecutive letters:

  • The gap between Z (26) and X (24) is $26 - 24 = 2$.
  • The gap between X (24) and U (21) is $24 - 21 = 3$.
  • The gap between U (21) and Q (17) is $21 - 17 = 4$.

The differences are increasing by one each time: 2, 3, 4. The next difference in this pattern should be 5.

To find the next letter, we subtract this next difference (5) from the position of the last letter (Q=17):

$17 - 5 = 12$

The 12th letter of the alphabet is L.

Final Answer

Therefore, the next letter in the sequence is L.
