Analyzing the Sequence Pattern

The question asks to identify the next term in the given alphabetical sequence: CBA, DCB, EDB, FEB, ? We can solve this by analyzing the pattern of change for each letter position within the terms.

Step-by-Step Pattern Analysis

  1. First Letter Progression:

    Observe the first letter of each term: C, D, E, F. This is a straightforward sequence where each letter is the immediate successor of the previous one in the alphabet (C+1=D, D+1=E, E+1=F). Following this pattern, the next letter must be G.

  2. Second Letter Progression:

    Now, examine the second letter of each term: B, C, D, E. Similar to the first letter, this sequence progresses alphabetically (B+1=C, C+1=D, D+1=E). Therefore, the next letter in this position is F.

  3. Third Letter Progression:

    Consider the third letter of each term: A, B, B, B. The pattern here is that the letter changes from A to B between the first and second terms. Subsequently, the letter remains B for the third and fourth terms. Based on this observed pattern, the next letter will continue to be B.

Determining the Next Term

By combining the next letter determined for each position:

  • First letter: G
  • Second letter: F
  • Third letter: B

Therefore, the next term in the sequence is GFB.
