Hi,
See the pattern here ,
It is like n × ( n + 1 )
1 ) if n = 2 then 2 × (2 +1 ) = 2 × 3 = 6
2 ) if n = 3 then 3 × ( 3 + 1 ) = 3 × 4 = 12
3 ) If n = 4 then 4 × ( 4 + 1 ) = 4 × 5 = 20
4 ) if n = 5 then 5 × ( 5 + 1 ) = 5 × 6 = 30
5 ) if n = 6 then 6 × ( 6 + 1 ) = 6 × 7 = 42
6 ) if n = 7 then 7 × ( 7 + 1 ) = 7 × 8 = 56
7 ) if n = 8 then 8 × ( 8 + 1 ) = 8 × 9 = 72
8 ) if n = 9 then 9 × ( 9 + 1 ) = 9 × 10 = 90
Therefore ,
Required answer is
9 = 90
I hope this helps you.
