Reasoning – Inserting The Missing Character
What is Inserting the Missing Character?
These questions present you with a pattern of numbers, letters, or both arranged in a square or matrix. You must analyze the pattern and insert the missing character to complete the logic.
Types of Patterns
1. Row-wise or column-wise arithmetic patterns.
2. Diagonal relationships.
3. Alphabetical sequence based on positions.
4. Mathematical operations within grid cells.
Example Questions
- A grid:
\(\begin{bmatrix}2 & 4 & 6 \\ 3 & 6 & 9 \\ 4 & ? & 12\end{bmatrix}\)
Answer: Answer: 8 (Each row is a multiplication table)
- A grid:
\(\begin{bmatrix}A & C & E \\ G & I & K \\ M & ? & Q\end{bmatrix}\)
Answer: Answer: O (Skipping 1 letter each time)
Exam Tips
- Observe each row, column, and diagonal for operations.
- Convert letters to positions (A=1, B=2, ..., Z=26) for alphabet questions.
- Break complex grids into smaller sections and test hypotheses.
- Look for common number operations like \(+\), \(−\), \(\times\), \(\div\).
Common Mistakes
- Assuming patterns row-wise only — check column and diagonal logic too.
- Missing basic number patterns due to focus on letters.
- Overlooking alternate cell relationships.
Quick Revision Checklist
- Practice 3×3 and 4×4 grid problems.
- Review letter-to-number conversions.
- Check all directions: row, column, diagonal.
- Try reverse-checking your answer to validate.
Summary: Inserting the Missing Character tests analytical observation and arithmetic/alphabetic reasoning. It is important to explore multiple patterns to find the correct logic.
