Aptitude - Odd Man Out and Series - Discussion

@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.

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

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.

Very helpful to me.

Not getting this, Please explain me.

see friends..

second no - first no.
third no - second no ..
series go like that ..
that is
13-8=5
21-13=8
32-21=11

47-32=15
63-47=16

see in about two line we have to 14 and 17 respectively..
so that the series contiunes as the difference of 3 after subtracting the next no from previous no ..
when we replace 47 by 46 ..

46-32=14
63-46=17
83-63=20..

so the 5.. 8.. 11.. 14.. 17... 20.. the difference is 3..

i think u have clear ur doubts friends... thank u ..

5, 2, 13, 29, 17, 8, 21 find add man out.

@Nagendramurthy.

Your solution is correct. Thanks.

I am not understanding it. Please explain me to get it.
