 Narrative
 The first partner spins to get a group of coins. They write a question that compares the amount they spun to a different group of coins that they make up.

Answer: 
Yes. In this activity, students write word problems that compare coin amounts.

Now, determine whether the following problem or activity can enable students to understand the concepts or skills in the provided description.

standard_description: Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.
problem_activity: Problem 1
Consider the sequence below.
$${1, \space1,\space 2,\space 3,\space 5,\space 8,\space 13,\space 21, \space34, …}$$
a.   Describe the pattern that you notice. How is each next term determined?
b.   This pattern is famously called the Fibonacci sequence. Write a recursive formula to represent the Fibonacci sequence. Write a formula in sequence notation using
$${a_n}$$
and in formula notation using
$${f(n)}$$
.
c.   If
$${a_{15}=610}$$
and
$${a_{16}=987}$$
, what are the values of
$${a_{17}}$$
and
$${a_{14}}$$
?
Problem 2
For each sequence below, write a recursive formula, in both sequence notation and function notation, to represent the sequence.
a.
$${18,\space 13,\space 8,\space 3,\space -2,\space …}$$
b.
$${4,\space 12,\space 36,\space 108,\space 324,\space …}$$
Problem 3
A sequence is given by an explicit formula, as shown below, where
$$n$$
represents the term number.
$$a_n=4n-1$$
for
$$n\geq1$$
a.   Write the first five terms in the sequence.
b.   Write a recursive formula to represent the sequence.
