Identifying the Alphabetical Pattern

The question asks us to find a pair of letter groups that follows the same logical pattern as the two given examples: QTW-SVY and BBE-ADG. We need to figure out the relationship between the first group and the second group in each pair.

Analyzing the First Pattern: QTW-SVY

Let's examine the first pair, QTW-SVY. We can look at the positions of the letters in the alphabet (A=1, B=2, ..., Z=26):

• Q is the 17th letter.
• T is the 20th letter.
• W is the 23rd letter.

Now let's look at the second group, SVY:

• S is the 19th letter.
• V is the 22nd letter.
• Y is the 25th letter.

Let's find the difference in positions:

The pattern observed in the first pair is that each letter in the first group is shifted forward by 2 positions in the alphabet to get the corresponding letter in the second group.

Analyzing the Second Pair: BBE-ADG

Let's check if the second pair, BBE-ADG, follows the same '+2' pattern:

• B (2) -> A (1): Difference is $1 - 2 = -1$.
• B (2) -> D (4): Difference is $4 - 2 = +2$.
• E (5) -> G (7): Difference is $7 - 5 = +2$.

This pair does not consistently follow the '+2' shift pattern observed in the first pair. However, since the question states both pairs follow the *same* pattern, and we need to select an option that follows *the* pattern, we should rely on the clearer pattern identified in QTW-SVY (+2 shift) and check the options against it.

Evaluating the Options Based on the '+2' Pattern

We are looking for a pair where each letter of the first group is shifted forward by 2 positions to get the second group.

1. Option 1: CFI-DHJ
   • C (3) to D (4): $+1$ (Incorrect)
2. Option 2: CFI-EHK
   • C (3) to E (5): $+2$
   • F (6) to H (8): $+2$
   • I (9) to K (11): $+2$

   This option perfectly matches the '+2' shift pattern.

3. Option 3: CEG-EHK
   • C (3) to E (5): $+2$
   • E (5) to H (8): $+3$ (Incorrect)
4. Option 4: CEG-DGJ
   • C (3) to D (4): $+1$ (Incorrect)

Conclusion

Based on the analysis of the first pair (QTW-SVY), the consistent pattern is adding 2 to the alphabetical position of each letter. Option 2 (CFI-EHK) is the only pair that follows this exact pattern.
