Very complicated math

[Marty]

Oh yeah btw me and my friends had a theory ongoing that the formating might be wrong o.o!
Because it says something about horizontal lines like mentioned before so I would take that into consideration maybe.

It is indeed horribly formatted. This is what it's supposed to look like:

            76
            94
34 78 56 12 ?
            49
            58

Looking at the "word" question immediately below this one in the linked PDF confirms this was the intended format for these questions.

SEE THIS PUTS EVERYTHING IN A NEW LIGHT!!
I figured that it had to be a formatting problem and now everything makes sense that its actually 67

Tho I still don't know how 67 fits into the horizontal line :o

yea we solved this 10 hours ago but ice tea is a slowpoke... stick to lc bro

It fits in the horizontal line because the ones digit follows the tens digit on the number line.

Formatting makes this simple as hell

I had an aneurism when I first saw the question, and then a second aneurism when I realized how simple the question was when written properly.
