Understanding Letter Series Patterns and Reasoning
This question asks us to find the relationship between pairs of terms and apply the same relationship to a third term. This type of problem falls under logical reasoning, specifically letter series or coding-decoding.
We are given three pairs/terms:
- TACKLE : TCCMLG
- JACKET : JCCMEV
- NEPTUNE : ?
Our task is to discover the transformation rule that changes TACKLE into TCCMLG and JACKET into JCCMEV, and then use that rule to find the term related to NEPTUNE.
Analyzing the Relationship in the First Pair: TACKLE to TCCMLG
Let's examine the transformation letter by letter, noting the position change in the alphabet for each corresponding letter:
| Original Letter (TACKLE) | Transformed Letter (TCCMLG) | Change |
|---|---|---|
| T | T | No change (+0) |
| A | C | A → B → C (+2 letters) |
| C | C | No change (+0) |
| K | M | K → L → M (+2 letters) |
| L | L | No change (+0) |
| E | G | E → F → G (+2 letters) |
The pattern observed in the first pair is a sequence of positional shifts: +0, +2, +0, +2, +0, +2.
Verifying the Pattern with the Second Pair: JACKET to JCCMEV
Now, let's apply the same pattern (+0, +2, +0, +2, +0, +2) to the letters of JACKET and see if it results in JCCMEV.
| Original Letter (JACKET) | Applied Shift | Resulting Letter | Transformed Letter (JCCMEV) |
|---|---|---|---|
| J | +0 | J | J |
| A | +2 | C | C |
| C | +0 | C | C |
| K | +2 | M | M |
| E | +0 | E | E |
| T | +2 | V | V |
Applying the pattern (+0, +2, +0, +2, +0, +2) to JACKET gives JCCMEV, which matches the second term provided. This confirms that our identified pattern is correct.
Applying the Pattern to the Fifth Term: NEPTUNE
The word NEPTUNE has 7 letters. We will apply the same alternating pattern of shifts (+0, +2) to each letter, extending it for the 7 letters: +0, +2, +0, +2, +0, +2, +0.
| Original Letter (NEPTUNE) | Applied Shift | Resulting Letter |
|---|---|---|
| N | +0 | N |
| E | +2 | G (E → F → G) |
| P | +0 | P |
| T | +2 | V (T → U → V) |
| U | +0 | U |
| N | +2 | P (N → O → P) |
| E | +0 | E |
Applying the pattern to NEPTUNE results in the term NGPVUPE.
Matching the Result with the Options
Let's compare our derived term, NGPVUPE, with the given options:
- Option 1: PEPTVOE
- Option 2: PERTWNG
- Option 3: NFGPVUP
- Option 4: NGPVUPE
Our result NGPVUPE matches Option 4.
Conclusion
The relationship between the terms is a letter-by-letter transformation following the pattern of shifts: +0, +2, +0, +2, and so on, for the position of the letter in the English alphabet. Applying this pattern to NEPTUNE yields NGPVUPE.

Additional Information: Types of Letter Series Patterns
Letter series and analogy questions can involve various types of patterns. Recognizing these can help solve problems quickly:
- Alphabetical Position Shift: Adding or subtracting a fixed number (like in this problem, +2) or a variable number to the letter's position (A=1, B=2, etc.).
- Alternating Patterns: Different rules applied to alternate letters (e.g., +2, +3, +2, +3...) or alternate positions (odd/even).
- Skipping Letters: Skipping a fixed or increasing/decreasing number of letters between terms.
- Reversal: Letters might be reversed or rearranged.
- Vowel/Consonant Based: Patterns might apply only to vowels or consonants.
- Combination of Rules: A mix of the above patterns.
Solving these problems requires careful observation and systematic testing of potential rules based on the changes between the given terms.
