Odd One Out: Number Properties Analysis
The question asks to identify the number that does not follow the pattern of the others among the given options. We need to analyze the properties of each number.
Number Analysis
-
289: This number is a perfect square. It is the result of $17 \times 17$ ($17^2$).
-
347: This number is not a perfect square. Testing divisibility shows it is a prime number.
-
361: This number is a perfect square. It is the result of $19 \times 19$ ($19^2$).
-
441: This number is a perfect square. It is the result of $21 \times 21$ ($21^2$).
Identifying the Odd One Out
Three of the numbers (289, 361, and 441) are perfect squares.
The number 347 is a prime number and not a perfect square.
Therefore, 347 is the odd one out based on this property.
Conclusion
The odd one out is 347 because it is a prime number, while the others are perfect squares.
