The questions in this exercise are from videos in the integral calculus playlist not the precalc playlist where the exercise is placed. The videos in "Stuck, watch a video" are also in the integral calc playlist on series and sequences not the precalc playlist series and sequences. Either the videos should be put in the precalc playlist or this exercise should be moved to the integral calc series and sequences section.
