Brain Test Level 343
Question & Solution
The question presents a sequence of modified equations: 2 + 3 = 8, 3 + 4 = 15, 4 + 5 = 24, 5 + 6 = ?
The Pattern
The rule applied to these equations is A + B = A × (B + 1), which is equivalent to (A × B) + A.
- 2 + 3 = (2 × 3) + 2 = 6 + 2 = 8
- 3 + 4 = (3 × 4) + 3 = 12 + 3 = 15
- 4 + 5 = (4 × 5) + 4 = 20 + 4 = 24
Level 343 Answer
Applying the same pattern to the final equation (5 + 6):
5 + 6 = (5 × 6) + 5 = 30 + 5 = 35.
Input the number 35.

Medium
PRO TIP
The answer is found by multiplying the first number by the successor of the second number. (A + B = A * (B + 1))
