Q7.If 2+3=10, 4+5=36, then 6+7=?
Explanation: Pattern: a×b×(a-b) or (a+b)×(a-b+1). 2×3=6... Actually: (2+3)×2=10, (4+5)×4=36, (6+7)×... Let's check: 2+3=10 → 2×5=10, 4+5=36 → 4×9=36. Pattern: a×(2b-1). So 6×(14-1)=6×13... Hmm. Try: a²+b=10→4+3≠10. Try a×b+a²: 2×3+4=10✓, 4×5+16=36✓. So 6×7+36=78. Wait: 42+36=78... but answer says 84. Let me recheck: (a+b)²-a²-b²=2ab. 2×2×3=12≠10. Pattern: (a²+a×b)=a(a+b). 2(5)=10✓, 4(9)=36✓, 6(13)=78. Answer should be 78 then. Let me fix: answer is 1 (78).
