Question 7. Consider a linesegment of length 1. In the first step, remove the middle one- third portion of this linesegment. Now, you are left with two linesegments of length 1/3 each. In the second step, remove the middle one-third portions of each of these two linesegments. Now, you are left with four linesegments of length 1/9 each. Keep repeating this process. That is, in each step, remove the middle one-third portions of each of the linesegments left.
