i think in case of odd ....

make 3 sets for eg - if there are 9 balls ,make three sets
of 4 ,4 and 1 balls.

now weigh the sets having 4 balls(i.e.1st and 2nd),if weigh
comes equal then the least weight ball is the ball of 3rd set.

if weigh are not equal then we"ll come to knoe that the 3rd
set ball is not the least 1,thus now we are left with 8
balls,now the set which weigh less divide it into 2 parts
,further weigh them ,now we left with 2 balls,finally weight
them will get the least weigh ball

complete the series: a c b d f e g i __
