The Creative Math Puzzle: If 5 + 2 = 30, 7 + 3 = 52; 8 + 4 = 72; 10 + 2 = 102, Then What is 9 + 5?

In this creative math puzzle, the result of the addition doesn’t follow regular arithmetic. There’s a hidden pattern that needs to be discovered to find the answer. The pattern involves multiplying the first number and then adding the second number.

If:

5 + 2 = 30

7 + 3 = 52

8 + 4 = 72

10 + 2 = 102

Then, what is the result of 9 + 5?

Pattern Analysis:

Let’s break down the pattern:

1. 5 + 2 = 30
   • The pattern is: (5 × 6) + 2 = 30. The first number is multiplied by 6, and then the second number is added.
2. 7 + 3 = 52
   • The pattern is: (7 × 7) + 3 = 52. The first number is multiplied by 7, and then the second number is added.
3. 8 + 4 = 72
   • The pattern is: (8 × 8) + 4 = 72. The first number is multiplied by 8, and then the second number is added.
4. 10 + 2 = 102
   • The pattern is: (10 × 10) + 2 = 102. The first number is multiplied by 10, and then the second number is added.

Applying the Pattern to 9 + 5:

Using the same pattern, we multiply the first number (9) by 9, and then add the second number (5):

• 9 × 9 + 5 = 86.

Thus, the answer to 9 + 5 is 86.

Conclusion:

In this puzzle, the result isn’t from simple addition. There is a hidden pattern where the first number is multiplied by an increasing factor, and then the second number is added. Using this pattern, we find that 9 + 5 = 86.
