XZA-YAB
CEF-DFG
Pattern Logic: XZA-YAB & CEF-DFG
The task is to find a pair of letter sequences that mirrors the pattern established by the two examples provided: $XZA-YAB$ and $CEF-DFG$.
Pattern Rule Identification
First, let's decode the relationship within the given pairs:
Example 1: $XZA$ -> $YAB$
- X shifts to Y (Next letter, or +1 position)
- Z shifts to A (Next letter, wrapping around from Z to A, or +1 position)
- A shifts to B (Next letter, or +1 position)
Example 2: $CEF$ -> $DFG$
- C shifts to D (+1 position)
- E shifts to F (+1 position)
- F shifts to G (+1 position)
The rule is clear: each letter in the first sequence is advanced by 1 position in the alphabet to form the second sequence. We can denote this as a '$+1$' shift.
Option Evaluation
Let's test each option against the '$+1$' pattern:
| Option | Sequence 1 | Sequence 2 | Analysis (Seq1 + 1 = Seq2?) |
|---|---|---|---|
| 1 | JKK | KMN | J + 1 = K (Match) K + 1 = L (No Match - M) K + 1 = L (No Match - N) |
| 2 | JLM | JMM | J + 1 = K (No Match - J) L + 1 = M (Match) M + 1 = N (No Match - M) |
| 3 | JLM | KMN | J + 1 = K (Match) L + 1 = M (Match) M + 1 = N (Match) |
| 4 | JKK | JLM | J + 1 = K (No Match - J) K + 1 = L (Match) K + 1 = L (No Match - M) |
Matching Pair Conclusion
The evaluation shows that only Option 3, the pair $JLM-KMN$, perfectly fits the '$+1$' alphabetical shift pattern observed in the initial examples $XZA-YAB$ and $CEF-DFG$.
