A long resistance wire is divided into 2n parts. Then n parts are connected in series and the other n parts in parallel separately. Both combinations are connected to identical supplies. Then the ratio of heat produced in series to parallel combinations will be -

Find the term of the series 25,22(3)/(4),20(1)/(2),18(1)/(4) which is numerically the smallest.
