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

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

    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

    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

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

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

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