Question 13

A bug (of negligible size) starts at the origin on the coordinate plane. First it moves $1$ unit right to $(1,0).$ Then it makes a $90^\circ$ turn counterclockwise and travels $\frac12$ a unit to $(1,\frac12).$ If it continues in this fashion, each time making a $90^\circ$ turn counterclockwise and traveling half as far as in the previous move, to which of the following points will it come closest?
  1. $(\frac23,\frac23)$
  2. $(\frac45,\frac25)$
  3. $(\frac23,\frac45)$
  4. $(\frac23,\frac13)$
  5. $(\frac25,\frac45)$
