This question was previously asked in
SSC CGL 2025 Tier 2 Paper 1 Question Paper (19-Jan-2026)
The correct answer is
G

The question asks to find the missing letter in the alphabetical sequence: A, C, E, ?, I.

Alphabetical Pattern Identification

Observe the given letters:

  • A
  • C
  • E
  • ?
  • I

Pattern Analysis

Analyze the relationship between consecutive letters:

  • From A to C, the letter B is skipped.
  • From C to E, the letter D is skipped.

The pattern is that each letter is separated by exactly one skipped letter in the alphabet.

Finding the Missing Letter

Applying this pattern:

  • After E, the next letter in the alphabet is F.
  • Skipping F, the following letter is G.

Let's check if G fits the sequence:

  • A (skip B) C (skip D) E (skip F) G (skip H) I

The sequence A, C, E, G, I follows the established pattern.

Conclusion

The missing letter is G.
