IF 1+2 = 3
3 + 4 = 21
5 + 6 = 55
Then 4 + 5 = ?
Answer is 36
Explanation:
1 + 2 => (1)^2 + (1*2) = 3
3 + 4 => (3)^2 + (3*4) = 21
5 + 6 => (5)^2 + (5*6) = 55
Thus 4 + 5 => (4)^2 + (4*5) = 36

36
Hi all, may you all help me with this . Thanks
2 + 5 = 7
3 + 6 = 4
4 + 7 = 21
5 + 8 = -32
6 + 9 = ???
36
i think defozo is correct
36
I think it could be even:
1+2=3 (3*1=3)
3+4=7 (7*3=21)
5+6=11 (11*5=55)
Then 4+5=9 (9*7=63)
Last statement should be 9*4 = 36 🙂
3 + 4 => 3*(3+4) = 21 GREAT !!!
But 3+4 = 12 and 12 *3 = 36
36 != 21 I think
Sorry, I see bad.
It’s “+” not “*”
@2ec15b5af274b68408e6d0e050c2c7dd:disqus it happens, thats why these are puzzles, thanks for your comment.
it can solved also like below:
1 + 2 => 1*(1+2) = 3
3 + 4 => 3*(3+4) = 21
5 + 6 => 5*(5+6) = 55
Thus 4 + 5 => 4*(4+5) = 36
