Different Term Identification
The goal of this question is to identify which number in the list does not share a common mathematical property with the others. This requires analyzing the properties of each given number.
Number Options Analysis
The options provided are:
- Option 1: 49
- Option 2: 64
- Option 3: 90
- Option 4: 81
We will look for a pattern among these numbers.
Perfect Squares Pattern
A common pattern in such questions is whether the numbers are perfect squares. A perfect square is a number that results from multiplying an integer by itself.
- 49: This number can be obtained by squaring the integer 7. Calculation: \(49 = 7 \times 7 = 7^2\). So, 49 is a perfect square.
- 64: This number can be obtained by squaring the integer 8. Calculation: \(64 = 8 \times 8 = 8^2\). So, 64 is a perfect square.
- 81: This number can be obtained by squaring the integer 9. Calculation: \(81 = 9 \times 9 = 9^2\). So, 81 is a perfect square.
Outlier: Number 90
Now, let's check the number 90 for the same property:
We need to determine if 90 is a perfect square.
- Consider the squares of integers near the square root of 90.
- We know that \(9^2 = 81\).
- The next integer square is \(10^2 = 100\).
- Since 90 falls between 81 and 100, it cannot be represented as the square of an integer (\(n^2\)).
- Therefore, 90 is not a perfect square.
Term Conclusion
By analyzing the options, we found that 49, 64, and 81 are all perfect squares. The number 90 does not fit this pattern because it is not a perfect square. Consequently, 90 is the different term in the list.
