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

• Arithmetic

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

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

Does this graph show an arithmetic or a geometric sequence?

• Arithmetic

• Geometric

• Neither

• Both

Which sequence type, and common ratio/difference is correct for the table?

• arithmetic

  common ratio = 2

• geometric

  common ratio = 2

• arithmetic

  common difference = 2

• geometric

  common difference = -2

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.

On a scale of 1-5, 1 meaning "I have no clue what is going on" to 5 meaning "I got it completely," how would you rate your understanding of identifying Geometric  Sequences: Graphing & Word Problems ?

• 1

• 2

• 3

• 4

• 5

Write the explicit formula for the geometric sequence.

• a_n = 4(3)^n-1

• a_n = 3(4)^n-1

• a_n = -4(3)^n-1

• a_n = 3(-4)^n-1
