CPM Homework Help : CCAA8 Problem 5-105

For this problem, refer to the sequences graphed below.

# $1$ A first quadrant coordinate plane with x axis labeled as n scaled from 0 to 6 and y axis labeled as t of n scaled from 0 to 17. The discrete graph has the following 6 points: (0, comma 16), (1, comma 13), (2, comma 10), (3, comma 7), (4, comma 4), (5, comma 1).

# $2$ A first quadrant coordinate plane with x axis labeled as n scaled from 0 to 6 and y axis labeled as t of n scaled from 0 to 17. The discrete graph has the following 7 points: (0, comma 16), (1, comma 9), (2, comma 4), (3, comma 1), (4, comma 0), (5, comma 1), (6, comma 4).

# $3$ A first quadrant coordinate plane with x axis labeled as n scaled from 0 to 6 and y axis labeled as t of n scaled from 0 to 17. The discrete graph has the following 7 points: (0, comma 16), (1, comma 8), (2, comma 4), (3, comma 2), (4, comma 1), (5, comma 0.5), & (6, comma 0.25).

Identify each sequence as arithmetic, geometric, or neither.
Hint (a):
Make a list of the $y$ -values for each graph. How are these values changing?
Answer (a):
Graph # $2$ : neither
If it is arithmetic or geometric, describe the sequence generator.

Hint 1(b):
The sequence generator is the number that is being added or multiplied each time.
Hint 2(b):
Your answer for Graph # $3$ should be a factor.
