A Curious Pattern Indeed

Curated and Reviewed by Lesson Planet

1, 2, 4, 8, 16, 31 ... hold it, that does not seem right. The resource presents the pattern of the number of sections created in a circle by connecting ever-increasing numbers of points on the circle. The video points out that the pattern begins in powers of two but breaks from the pattern after only six iterations. The presenter raises the question why and promises a more complete discussion in later videos.
