To solve this series, we need to identify the pattern or relationship between the given pairs of numbers.
Let's analyze the given pairs one by one:
1. 7, 2 = 59
The first number (7) is multiplied by itself and then subtracted by the square of the second number (2^2 = 4).
So, 7^2 - 4 = 49 - 4 = 45
2. 5, 3 = 28
The first number (5) is multiplied by itself and then subtracted by the square of the second number (3^2 = 9).
So, 5^2 - 9 = 25 - 9 = 16
3. 9, 1 = 810
The first number (9) is multiplied by itself and then subtracted by the square of the second number (1^2 = 1).
So, 9^2 - 1 = 81 - 1 = 80
4. 2, 1 = 13
The first number (2) is multiplied by itself and then subtracted by the square of the second number (1^2 = 1).
So, 2^2 - 1 = 4 - 1 = 3
From the above analysis, we can observe that the pattern is:
(first number)^2 - (second number)^2 = result
Now, let's apply this pattern to the missing pair: 5, 4 = ?
Using the pattern, we have:
5^2 - 4^2 = 25 - 16 = 9
Therefore, the missing pair is 5, 4 = 9, which corresponds to option (a).
Let's analyze the given pairs one by one:
1. 7, 2 = 59
The first number (7) is multiplied by itself and then subtracted by the square of the second number (2^2 = 4).
So, 7^2 - 4 = 49 - 4 = 45
2. 5, 3 = 28
The first number (5) is multiplied by itself and then subtracted by the square of the second number (3^2 = 9).
So, 5^2 - 9 = 25 - 9 = 16
3. 9, 1 = 810
The first number (9) is multiplied by itself and then subtracted by the square of the second number (1^2 = 1).
So, 9^2 - 1 = 81 - 1 = 80
4. 2, 1 = 13
The first number (2) is multiplied by itself and then subtracted by the square of the second number (1^2 = 1).
So, 2^2 - 1 = 4 - 1 = 3
From the above analysis, we can observe that the pattern is:
(first number)^2 - (second number)^2 = result
Now, let's apply this pattern to the missing pair: 5, 4 = ?
Using the pattern, we have:
5^2 - 4^2 = 25 - 16 = 9
Therefore, the missing pair is 5, 4 = 9, which corresponds to option (a).
