The answer to the puzzle is 41.

The hidden pattern in these equations follows a specific formula. For every equation A + B = C, the rule is to multiply the two numbers together, and then subtract the difference between the second number and the first number.

Formula: (A × B) – (B – A) = C

Let’s test this pattern on the provided examples:

• 2 + 3 = 5: Multiply: 2 × 3 = 6

  • Difference: 3 – 2 = 1

  • Subtract: 6 – 1 = 5

• 3 + 7 = 17: Multiply: 3 × 7 = 21

  • Difference: 7 – 3 = 4

  • Subtract: 21 – 4 = 17

• 4 + 5 = 19: Multiply: 4 × 5 = 20

  • Difference: 5 – 4 = 1

  • Subtract: 20 – 1 = 19

• 5 + 8 = 37: Multiply: 5 × 8 = 40

  • Difference: 8 – 5 = 3

  • Subtract: 40 – 3 = 37

Following this exact logic for the final equation:

• 6 + 7 = ?

  • Multiply: 6 × 7 = 42

  • Difference: 7 – 6 = 1

  • Subtract: 42 – 1 = 41
