Understanding Number Analogies and Finding Patterns
Number analogy questions test your ability to find a relationship between two numbers and apply that same relationship to a third number to find a missing fourth number. The given analogy is:
\(6 : 252 \;\;::\;\; 5 : ?\)
This means we need to discover the pattern or rule that connects 6 to 252, and then use that same rule to find the number that relates to 5.
Analyzing the Relationship between 6 and 252
Let's examine how 6 might be related to 252. We can consider basic mathematical operations like multiplication, squaring, cubing, addition, or subtraction, or a combination of these.
- If we multiply 6 by some number to get 252: \(252 \div 6 = 42\). The relationship could be multiplying by 42. If we apply this to 5: \(5 \times 42 = 210\). However, 210 is not one of the options.
- Let's consider powers of 6:
- \(6^2 = 36\)
- \(6^3 = 216\)
Notice that 216 is quite close to 252. The difference is \(252 - 216 = 36\). Interestingly, 36 is \(6^2\).
This suggests a possible relationship: The second number is the cube of the first number plus the square of the first number.
Let the first number be \(n\). The relationship appears to be \(n^3 + n^2\).
Let's verify this rule with the first pair (6 : 252):
For \(n=6\):
\[6^3 + 6^2 = 216 + 36 = 252\]This matches the given relationship between 6 and 252.
Applying the Pattern to Find the Missing Number
Now, we apply the same rule \(n^3 + n^2\) to the third number, which is 5.
For \(n=5\):
\[5^3 + 5^2 = 125 + 25 = 150\]So, the missing number related to 5 is 150.
Checking the Options
Let's compare our calculated missing number (150) with the given options:
- 125
- 150
- 225
- 176
Our calculated value, 150, matches option 2.
Therefore, the relationship is \(n^3 + n^2\), and applying this to 5 gives 150.

| Concept | Description | Example (based on this problem) |
|---|---|---|
| Number Analogy | Identifying the relationship between a pair of numbers to find a related number for another given number. | 6 : 252 :: 5 : ? |
| Pattern Recognition | The process of finding the rule (mathematical operation or sequence) that connects the given pair. | Discovering the \(n^3 + n^2\) pattern for 6 and 252. |
| Applying the Rule | Using the identified pattern on the third number to find the fourth number. | Applying \(n^3 + n^2\) to 5 to get 150. |
Additional Information on Number Analogy Patterns
Number analogies can involve various types of patterns. Understanding these common patterns can help solve such questions faster.
- Arithmetic Operations: Simple addition, subtraction, multiplication, or division.
- Squares and Cubes: The relationship might involve squaring (\(n^2\)), cubing (\(n^3\)), or combinations like \(n^2+1\), \(n^3-1\), \(n^2+n\), \(n^3+n^2\), etc.
- Prime Numbers: The numbers might be prime numbers or related to their sequence.
- Digit Operations: The pattern might involve operations on the digits of the number (e.g., sum of digits, product of digits).
- Sequence Based: Numbers following a specific sequence like Fibonacci.
Always start by checking simple relationships and then move towards more complex ones involving powers or combinations of operations when solving number analogy problems.
