SSC CGL 2025 Tier 1 Question Paper (25-Sep-2025) (Shift 3)
The correct answer is
DJ

Sequence Pattern Explained: AG, BH, CI, ?

To find the next term in the sequence AG, BH, CI, we need to identify the pattern governing the letters.

Let's examine the sequence by considering the position of each term:

  • First Letters: The first letters of the terms are A, B, C. These are consecutive letters in the alphabet. The next letter in this alphabetical sequence is D.
  • Second Letters: The second letters of the terms are G, H, I. These are also consecutive letters in the alphabet. The next letter in this sequence is J.

Combining the next letter from each position (D from the first letter sequence and J from the second letter sequence), the next term in the series is DJ.

Therefore, the sequence continues as AG, BH, CI, DJ.
