Length of the given wire.
When lenght isvincreased then resistance of wire also increases as they are directly proportional to each other.

Answer:
The length of wire is doubled on itself and so the area get reduced to half. The resultant resistance will be 4 times.
The process is repeated and therefore the resistance will increase by 4 times. The total resistance will be increased to 16 times.
