• Neither

Find the explicit formula for the sequence shown in the graph.

Which type of sequence is shown in the graph?

• Arithmetic

• Geometric

• Neither

Is this the graph of an arithmetic or a geometric sequence?

• Arithmetic

• Geometric

Does this graph show an arithmetic or a geometric sequence?

• Arithmetic

• Geometric

• Neither

• Both

The graph of an arithmetic sequence is ​ ​ (a)   and the graph of a geometric sequence is ​ (b)   .

• linear

• exponential

Explain how you could use a graphing calculator to determine whether the data in the table to the right represents a geometric sequence.

• Multiply each term by the preceding term to see if there is a common ratio.

• Divide each term by the preceding term to see if there is a common ratio.

• Subtract each term from the preceding term to see if there is a common difference.

• Add each term to the preceding term to see if there is a common difference.
