13-8 = 5.
21-13 = 8.
32-21 = 11.
x-32 = 14.
63-x = 17.
83-63 = 20.
(5,8,11,14,17,20 ) each time increase by 3.
So there, x should be equal to 46(i.e., x=46).
I hope you understood now.

@Manjeeth
If you see the difference;
8-13 is 5
13-21 is 8
21-32 is 11
Now if you see the no: 5 8 and 11
=> 5+3==>8.
8+3==>11.
So the now next no after adding 3 will be 11 +3 ==>14, but if u see the diff between 32 and 47 it is 15 which is wrong. So the ans will be 47.

Numbers are arranged like "even odd, odd even, even odd, odd even" 47 is the only one that doesn't follow this.
