Hard brain teaser to challenge your pattern recognition

Here’s a quick but hard brain teas­er to chal­lenge your abil­i­ty to find a pat­tern. In the table below, each row across fol­lows the same pat­tern. See if you can dis­cern the pat­tern and fill in the miss­ing num­ber in the bot­tom row.

For added chal­lenge, time how long it takes you to com­plete the puz­zle. Then, pass it along to some­one else and see who can solve it faster…

7 4 8
3 9 7
6 5 10
? 8 4

Have you solved it yet? If not, here’s a hint:

If you read your fig­ures like words in the West,
then mul­ti­ply your efforts and sub­tract the rest.

WARNING:  Answer and solu­tion fol­lows. Try to solve the puz­zle before you read fur­ther.

(7x4)-8 = 20

(3x9)-7 = 20

(3x8)-4 = 20

The answer is 3.
