Three of the following four number-pairs ale alike in a certain way and one is different. Find the odd one out.
865 : 722
Finding the Odd Number Pair Pattern
The objective here is to identify the number pair that is different from the others based on a specific underlying pattern or rule. We need to examine the relationship between the numbers within each pair to find this distinguishing characteristic.
Analyzing Number Pair Relationships
To find the pattern, let's calculate the difference between the first and second number in each pair. This helps in identifying a consistent mathematical relationship.
| Number Pair | Calculation (First Number - Second Number) | Result |
|---|---|---|
| 378 : 255 | $378 - 255$ | 123 |
| 756 : 633 | $756 - 633$ | 123 |
| 865 : 722 | $865 - 722$ | 143 |
| 967 : 844 | $967 - 844$ | 123 |
Identifying the Unique Number Pair
Observing the results from the calculations:
- The pair 378 : 255 has a difference of 123.
- The pair 756 : 633 has a difference of 123.
- The pair 967 : 844 has a difference of 123.
These three pairs share a common difference of 123.
However, the pair 865 : 722 has a difference of 143.
Therefore, the pair 865 : 722 stands out as it does not follow the established pattern of having a difference of 123.
Conclusion on the Odd Pair
The number pair 865 : 722 is the odd one out because the difference between its constituent numbers is 143, while the other pairs exhibit a difference of 123.
