A new drug and alcohol rehabilitation program performs outreach for members of the community. The number of participants for a 4 -week period is given in the table. (See Example 3) a. Based on the data given, does the number of participants follow an arithmetic progression? b. Write an expression for the n th term of the sequence representing the number of participants, where n represents the week number. c. Predict the number of participants in week 10 if this trend continues.

Predict the number of participants in week 10 if this trend continues.
Solution Summary: The author explains that if the difference between each term and its predecessor is the same or constant, the sequence is an arithmetic sequence.
A new drug and alcohol rehabilitation program performs outreach for members of the community. The number of participants for a
4
-week
period is given in the table. (See Example 3)
a. Based on the data given, does the number of participants follow an arithmetic progression?
b. Write an expression for the
n
th
term of the sequence representing the number of participants, where
n
represents the week number.
c. Predict the number of participants in week
10
if this trend continues.
Consider the following system of equations, Ax=b :
x+2y+3z - w = 2
2x4z2w = 3
-x+6y+17z7w = 0
-9x-2y+13z7w = -14
a. Find the solution to the system. Write it as a parametric equation. You can use a
computer to do the row reduction.
b. What is a geometric description of the solution? Explain how you know.
c. Write the solution in vector form?
d. What is the solution to the homogeneous system, Ax=0?
2. Find a matrix A with the following qualities
a. A is 3 x 3.
b. The matrix A is not lower triangular and is not upper triangular.
c. At least one value in each row is not a 1, 2,-1, -2, or 0
d. A is invertible.
