Sales-Fiction set out to stump the internet with this new "High IQ Intelligence Test." Some people could figure this out in seconds. Some struggled for a while before the light bulb went off. However, some just didn't see the answer at all.
Most Facebook users noted that intelligence isn't always mathematical ability but simply pattern recognition.
Still Stumped? The answer is...
Multiply. Add. Subtract.
For example: 8 x 2 = 16, 8 + 2 = 10, 8 - 2 = 6
You can follow that pattern to get each number in the series. Not exactly a life-altering question, but it's still a fun way to stump your Facebook friends!
