Aptitude - Odd Man Out and Series - Discussion

STEP1......8+5=13;
2......13+5+3=21;
3......21+5+3+3=32;
4......32+5+3+3+3=46 here in the series it is 47
5......46+5+3+3+3+3=63;
6......63+5+3+3+3+3+3=83; so 47 is wrong

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 ..

See friends,

Difference between 8 & 13 is 5.ie if v subtract 13-8 v get 5
Difference between 13 & 21 is 8.ie if v subtract 21-13 v get 8(5+3)
Difference between 21 &32 is 11.ie if v subtract 32-21 v get 11(8+3)

Likewise difference between 32 & 47 is 15.ie if v subtract 47-32 v get 15 But it doesnt satify the condition 11+3=14..hence 47 is wrong no..

Difference between 8 & 13 is 5.ie if v subtract 13-8 v get 5

I cant get this can you give better explanation.

The "difference between 47 and 63" is not 17 as stated. "Its 16"

Sorry I cant get this. Someone help how we got 14 to add.

Its very simple yaar. Difference betweenn 8 & 13 is 5, 13 & 21 is 8, 21 & 32 is 11. Add 3 numbers for all. Numbers you've to add is 5, 8, 11, 14, 17. 20. Got it?

I don't get it guys. Someone help please.
