Exercise 86 Page 277

a We will begin by explaining the difference between an arithmetic and geometric sequence.

If a sequence is arithmetic, there is a common difference between consecutive terms.
If a sequence is geometric, there is a common ratio between consecutive terms.

Let's start by investigating if it is arithmetic.

b Like in Part A, we will examine the differences between consecutive numbers.

c Like in Parts A and B, we will examine the difference between consecutive numbers.

d Like in Parts A through C, we have to examine if the sequence is linear.
