Chapter 8  Sequences and Series
"This chapter begins with a review of arithmetic and geometric sequences and their explicit and recursive formulas. Lessons provide opportunities for students to explore finite and infinite arithmetic series, and then finite and infinite geometric series are used to derive formulas to compute each type of series. Students will explore and analyze the common ratios of several infinite geometric series to understand under what conditions the series is either divergent or convergent. In the later part of the chapter, lessons provide opportunities for students to apply their understanding of geometric series to solve problems." Carnegie Textbook 
"Bees build honeycombs to hold larvae, pollen, and of course honey. Honeycombs are constructed of hexagonal cells that tile a surface with no overlaps or gaps."  Carnegie Textbook
