Series Completion Pattern Analysis

The question requires completing the alphabetical series: AZ, BY, CX, DW, ?

We need to identify the pattern governing the sequence.

Analyzing Letter Progressions

The series consists of pairs of letters. Let's examine the pattern for the first and second letters separately.

First Letter Pattern

The first letters of the pairs are A, B, C, D.

  • This sequence progresses alphabetically: A is the 1st letter, B is the 2nd, C is the 3rd, and D is the 4th.
  • The next letter in this sequence will be the 5th letter, which is E.

Second Letter Pattern

The second letters of the pairs are Z, Y, X, W.

  • This sequence progresses in reverse alphabetical order: Z is the 26th letter, Y is the 25th, X is the 24th, and W is the 23rd.
  • The next letter in this sequence will be the 22nd letter, which is V.

Determining the Next Term

By combining the next letter from the first progression (E) and the next letter from the second progression (V), the missing term in the series is EV.
