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

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.

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.

add 3 in 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.

8-13=value is 5.

add 3 in 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.
