Exercise 11 Page 579

Pay close attention to how terms are related and how each term is related to its position.

a_n=8-3n

Practice makes perfect

We want to write an explicit formula for the given sequence.

5, 2, -1, -4, ... We can see that the difference between consecutive terms is -3. With this information in mind, we can see that the value of a term is the difference between 8 and 3 times the term's position.

a_1	a_2	a_3	a_4	...	a_n
8-3* 1	8-3* 2	8-3* 3	8-3* 4	...	8-3* n
5	2	-1	-4	...
