## Only for Geniuses

too early for me! Tease Dat Brain!  What’s the answer: I’ll explain later, so don’t post your reasons, just your answers
Update 4/21: There’s 1 mathematical formula answer so far. The rest are patterns. So far 1 pattern seems to be most popular.
Update 4/17: There are at least 2 correct answers that can be proved. So everyone, if you post a number that hasn’t yet been posted, tell us why as well. Maybe there’ll be more than 2 answers…

9=9
It cannot equal anything else. 1=1, 2=2, 3=3, 4=4 etc

Umm dahh… It’s 90. It’s always the original number multiplied by the next number over it

And the question is “if”… It didn’t say 2=6… It said “if 2=6” so it doesn’t have to be 2=2

It is obviously 72. each answer is a multiplication of the one before so for example 2=6 means 2 x 3 = 6, 3 being the next number upwards. The reason 9 looks odd is they missed a step BUT if you use the rules the 9=72 – why? Because the missing number is 8 and 8 x 9 = 72. If they showed the whole sequence there would be 8=56 in between 7 and 9 – geddit…..?

72 isn’t correct with that way
1=3

and -1 ect….
9 = any number except 6,12,20,30,42,2,3,4,5,6. This is correct
So for me 9= 13
I think he will start again

60
(Add the double of the value to the sum before)

110

well i think its 90 cause if you do like this :
2 x 3 = 6
3 x 4 = 7
4 x 5 = 20
5 x 6 = 30
6 x 7 = 42
then its got to be..
9 x 10 = 90

😀 all the numbers got to be multiplied with the number over it 😀

Using the pattern provided, 9=81

Difference between 6&2 is 4(2 square), similarly difference between 12&3 is (3 square) and finally difference between 58&9 is(7 square)
