From the problem we find that the number on the left hand side of the '=' sign when multiplied by its consecutive next number in the natural number set, we get the right hand side number.
The number next to 2 is 3, 2 * 3 = 6 therefore 2 = 6
Similarly 3 * 4 = 12 therefore 3 = 12
4 * 5 = 20 therefore 4 = 20
5 * 6 = 30 therefore 5 = 30
Since the number next to 9 is 10 , therefore we get 9 * 10 = 90
So 9 = 90
