Answer the following in 175 to 260 words in your commentary:

How does the graph of a line compare to an arithmetic sequence? What does the slope represent? How would you find the first term?

Use your best fit equation to make a formula for the nth term of an arithmetic sequence. The year will represent the number of the term, and your data value will be the value at that term.

Use your arithmetic equation to predict what the 2,050th term will be. Do you think this is a good estimate of what the real value will be? Why or why not?

How does the graph of an exponential equation compare to a geometric sequence? How would you find the common ratio? How would you find the first term (assuming the year is the number of the term)?

Use your best fit equation to make a formula for the nth term of a geometric sequence. The year will represent the number of the term, and your data value will be the value at that term.

Use your geometric equation to predict what the 2,050th term will be. Do you think this is a good estimate of what the real value will be? Why or why not?
