Question

Solve the following quiz (2=6, 3=12, 4=20 ....9=?)

Answer 1

2*3=6
3*4=12
similarly
9*10=90

Answer 2

the answer is 90 
because 2 = 6 ( 2 * 3 = 6)
 3 = 12 ( 3 * 4 = 12 )
4 = 20 ( 4 * 5 = 20 )
5 = 30 ( 5 *6 = 30)
6 = 42 ( 6 * 7 = 42 )
7 = 56 ( 7 * 8 = 56 )
8 = 72 ( 8 * 9 = 72 )
9 = 90 ( 9 * 10 = 90 )
   i hope it's correct and will help u.................................^_^
