Fibonacci dout regarding position of the number

as bhiyya says 5th fibonacci is 5 ,right;
in this question we need to find that what is the value of the series at the nth position , so as 0 1 1 2 3 5 and so on,
1st pos.= 0
2nd pos = 1
3rd pos = 1
4th pos =1
5th pos = 3;;

then he explains in the video that 5th fibonnaci is 5…
so i misunderstood or misplace something… kindly explain.

@thakur0_0 its just if you start n from 0 then 5th number is 5, if you start n from 1 then 6th number is 5
