Who can work this one out? Math Puzzle

My mind says its not 20 for some reason.

 

[sam.hunt0710]

20 ..... yes/no

 

[mynameis940]

In some logic it's 20, but it could be 10 as well, or maybe something else? Who knows..

 

[zagard]

sixteen??? or twenty i duno

 

[cyrsss]

--- first i thought 36 - => 20 is the answer !

 

[Technetik]

And the answer is 20 ;p

 

[Peter Ngo]

It is obviously 10.

 

[Zweistein]

My calculator says its 10

Why? It is the only one that has not been answered..and the previous answers were wrong

 

[FutureProofSeo]

Some logic 20, but probably some "unknown parameters" not pre-described. Theoretically accurate maths questions always reveal parameters in the question

Tried reverse image search, it seems this is an original edit (dammit!).

I'd say it's 20... 6x2 + 4x2 = 20
but... since nowhere it says that 4+4= 16, the answer could be 6x2+4=16

 

[Zwielicht]

The answer is 16. The first number is being multiplied by 4 each time with the second number in each math problem being "times 4" (which I will explicate in a moment). So in the case of the last number, which is 2/3 of the original "times 4" number (2.666666667) you would get 16.

• 5+5=20 (5x4=20)
• 6+6=24 (6x4=24)
• 7+7=28 (7x4=28)
• 8+8=32 (8x4=32)

So 6+4=16 (8x2.66666667=16)

36 is the answer as they're going up by 4 each time

 

[amarindia]

As per puzzle, i think it is 20

 

[mickyfu]

I would say 24.

 

[IamNRE]

Close but no cigar yet.

 

[TheVigilante]

is it 22 by any chance?

 

[zagard]

6+6=24 means each 6 is 12, the pic dun define 4 anywhere so 4 is a 4
12+4=16

 

[DiscoDax]

My first thought was 24 but obviously wrong. What about 20?

 

[Trepanated]

If 20 is not the answer, the only other straightforward answer I can think of is 28
