Understanding the Letter Pattern
The question asks us to find a pair of letter sequences that follows the same logical pattern as the two examples provided: XZA-YAB and CEF-DFG.
Let's examine the first example, XZA to YAB:
- The first letter X shifts to the next letter in the alphabet, Y.
- The second letter Z shifts to the next letter, which wraps around to A.
- The third letter A shifts to the next letter, B.
Now let's check the second example, CEF to DFG:
- The first letter C shifts to D.
- The second letter E shifts to F.
- The third letter F shifts to G.
The consistent pattern observed in both examples is that each letter in the initial sequence is replaced by the letter immediately following it in the alphabet (a +1 shift). For Z, the next letter is A.
Analyzing the Options for the Pattern
We need to test each option to see if it fits this +1 alphabet shift pattern:
-
Option 1: JKK-KMN
- J + 1 letter = K. This matches the first part (J -> K).
- K + 1 letter = L. This does NOT match the second part (K -> M).
- K + 1 letter = L. This does NOT match the third part (K -> N).
Therefore, Option 1 does not follow the pattern.
-
Option 2: JLM-JMM
- J + 1 letter = K. This does NOT match the first part (J -> J).
Therefore, Option 2 does not follow the pattern.
-
Option 3: JLM-KMN
- J + 1 letter = K. This matches the first part (J -> K).
- L + 1 letter = M. This matches the second part (L -> M).
- M + 1 letter = N. This matches the third part (M -> N).
All letters follow the +1 shift pattern. This option matches.
-
Option 4: JKK-JLM
- J + 1 letter = K. This does NOT match the first part (J -> J).
Therefore, Option 4 does not follow the pattern.
Identifying the Correct Pair
By applying the identified pattern (+1 letter shift for each position) to the options, we find that only Option 3 (JLM-KMN) correctly replicates the transformation seen in the original pairs.
