Homework, Page 739 37. The bungy-bungy tree grows an average of 2.3 cm per week. Write a sequence that represents the height of a bungy-bungy over the course of one-year if it is 7 meters tall today. Display the first four terms and the last two terms.
Homework, Page 739 43. If the first two terms of a geometric sequence are negative, then so is the third. Justify your answer. True, if the first two numbers are negative, then the common ratio must be positive and the multiplication of a negative number by a positive number yields another negative number.

9.5 Series
What you’ll learn about • Summation Notation • Sums of Arithmetic and Geometric Sequences • Infinite Series • Convergences of Geometric Series … and why Infinite series are at the heart of integral calculus.
Partial Sums Partial sums are the sums of a finite number of terms in an infinite sequence. In some instances, the partial sums approach a finite limit and the series is said to converge.

9.6 Mathematical Induction
What you’ll learn about • The Tower of Hanoi Problem • Principle of Mathematical Induction • Induction and Deduction … and why The principle of mathematical induction is a valuable technique for proving combinatorial formulas.
The Tower of Hanoi Solution The minimum number of moves required to move a stack of n washers in a Tower of Hanoi game is 2n – 1.
Principle of Mathematical Induction Let Pn be a statement about the integer n. Then Pn is true for all positive integers n provided the following conditions are satisfied: • (the anchor) P1 is true; • (inductive step) if Pk is true, then Pk+1 is true.
Example Proving a Statement Using Mathematical Induction Use mathematical induction to prove the statement holds for all positive integers.
Induction and Deduction • Induction - the process of using evidence from a particular example to draw conclusions about general principles • Deduction - the process of using general principles to draw conclusions about specific examples
