Brain teasers like this one have taken over social media, leaving thousands of people debating the correct answer.
At first glance, the equations seem simple—but the final line has many scratching their heads.
Here’s the puzzle:
1 + 5 = 62 + 6 = 143 + 7 = 245 + 11 = ?
Many people instinctively answer 16, but that’s exactly what makes this puzzle interesting.
The challenge isn’t about using normal addition—it’s about discovering the hidden pattern.
Look for the RuleEach equation builds on the one before it using the following pattern:
Result =
(First Number × Second Number) + First NumberLet’s test it:1 × 5 + 1 = 6 ✅2 × 6 + 2 = 14 ✅3 × 7 + 3 = 24 ✅Now apply the same rule to the final equation:5 × 11 + 5 = 55 + 5 = 60✅
Answer: 60
