## 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…

Thanks to SMS

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

9. 60
(Add the double of the value to the sum before)

10. 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 😀

12. Using the pattern provided, 9=81
