Logical Math Test and How to Reveal Hidden Patterns: When Simple Addition Doesn’t Apply!
In the Logical Math Test: If 4 + 3 = 27, 6 + 4 = 46; 9 + 2 = 81; 10 + 1 = 91, then what is 7 + 5?, the result is not the direct sum of the two numbers. There is a hidden pattern we need to identify first in order to find the answer. This test involves a series of numbers, and let’s try to see the pattern in the following examples:
If:
4 + 3 = 27
6 + 4 = 46
9 + 2 = 81
10 + 1 = 91
Then, what would be the result of 7 + 5?
Pattern Analysis in the Logical Math Test
From the given results, we see that each operation follows a specific rule, not just simple addition. Let’s break down the pattern:
- 4 + 3 = 27
- The pattern we find is: (4 × 6) + 3 = 27.
- Here, we multiply the first number by 6, then add the second number to get the result.
- 6 + 4 = 46
- The pattern is: (6 × 7) + 4 = 46.
- We multiply the first number by 7, then add the second number.
- 9 + 2 = 81
- The pattern is: (9 × 9) + 2 = 81.
- The first number is multiplied by 9, then the second number is added.
- 10 + 1 = 91
- The pattern used here is: (10 × 9) + 1 = 91.
- The first number is multiplied by 9, then the second number is added.

Applying the Pattern to 7 + 5
Now, based on the pattern above, let’s find the result of 7 + 5:
- Using the same pattern, we multiply the first number (7) by 8, then add the second number (5):
- 7 × 8 + 5 = 61.
So, based on this pattern, 7 + 5 = 61.

Conclusion
In this type of problem, the result is not derived from simple addition. There is a hidden pattern where the first number is multiplied by an increasing value in the sequence, then the second number is added. By understanding this pattern, we can determine that 7 + 5 = 61.
Problems like this not only test basic math skills, but they also challenge logical and analytical thinking to recognize hidden patterns behind the numbers.
