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

@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.

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.

It's very simple add three number for each last no.

8-13=value is 5.
5+3=8, so 13+=21,
8+3=11 ,so 21+11=32,
11+3=14,so 32+14=46,
14+3=17,so 46+27=63,
17+3=20,so 63+20=83,

So the wrong no is 47, real value is 46.
