Select the combination of letters which when sequentially placed in the blanks of the given series will complete the series. LMN _ LMN _ LM _ NL _ MMNN
LLML
Understanding the Letter Series Completion
This question asks us to identify the correct combination of letters that will complete the given series. To solve this type of problem, we need to look for a logical pattern in the sequence of letters. We will test the given options by placing the letters from each option into the blanks and observing the resulting series.
Analyzing the Given Series
The given letter series is: LMN _ LMN _ LM _ NL _ MMNN
There are four blanks in the series.
Testing the Options
We will substitute the letters from each option into the blanks. Let's test Option 2, which is provided as the correct answer: LLML.
The blanks are located at positions 4, 8, 11, and 14 when counted from the beginning of the series (L=1, M=2, N=3, \_=4, L=5, M=6, N=7, \_=8, L=9, M=10, \_=11, N=12, L=13, \_=14, M=15, M=16, N=17, N=18).
Inserting LLML into the blanks:
- Blank 1 (Position 4) → L
- Blank 2 (Position 8) → L
- Blank 3 (Position 11) → M
- Blank 4 (Position 14) → L
The completed series becomes: L M N L L M N L L M M N L L M M N N
Resulting series: LMNL LMNL LMMN LLMMNN
Identifying the Pattern
Let's examine the completed series: LMNL LMNL LMMN LLMMNN. We can observe the pattern by grouping the letters:
| Group | Letters | Observation |
|---|---|---|
| 1 | LMNL | Base sequence LMN + L |
| 2 | LMNL | Repeat of Group 1 |
| 3 | LMMN | Similar to LMN but with an additional M (LM + M + N) |
| 4 | LLMMNN | Seems to be a doubling of L, M, and N (LL + MM + NN) |
The series appears to follow a pattern where groups evolve. The first two groups are identical (LMNL). The third group introduces an extra 'M' (LMMN). The final group expands significantly, potentially doubling the core components (LLMMNN).
This pattern is consistent and logical given the sequence of letters provided in the correct option.
Conclusion
When the letters LLML are sequentially placed in the blanks of the given series LMN _ LMN _ LM _ NL _ MMNN, the resulting series LMNL LMNL LMMN LLMMNN forms a discernible pattern based on evolving groups of letters. Therefore, the combination LLML correctly completes the series.
Revision Table: Letter Series Patterns
| Pattern Type | Description | Example (Simple) |
|---|---|---|
| Repeating | A fixed block of letters repeats. | ABCABCABC |
| Increasing Length | Blocks repeat but increase in length. | AB AABB AAABBB |
| Alternating | Different blocks alternate. | ABABABAB |
| Evolving/Transforming | Blocks change based on a rule (e.g., adding letters, changing order, increasing counts). | As seen in this problem (LMNL, LMNL, LMMN, LLMMNN) |
Additional Information on Letter Series Reasoning
Letter series questions are common in logical reasoning sections of competitive exams. They test your ability to recognize patterns and sequences.
- Common Patterns: Patterns can involve repetition, alphabetical order (forward or backward), skipping letters, increasing or decreasing gaps, or combinations of these.
- Steps to Solve:
- Count the total number of letters and blanks.
- Divide the total number by common factors (e.g., 3, 4, 5, 6) to look for repeating blocks of a specific length.
- Examine the letters immediately before and after each blank.
- Test the options by filling the blanks one by one.
- Look for consistency in the pattern once an option is filled.
- Look for Clues: Repeating sub-sequences (like 'LMN' in this case) or increasing/decreasing counts of specific letters can provide hints about the underlying rule.
