Given the sequence 2, 4, 8, 16, 32.... What is the third term?

• 2

• 4

• 8

• 16

Given the sequence 2, 4, 8, 16, 32.... What is the initial term, a₀?

• 1

• 2

• 4

Given the sequence 2, 4, 8, 16, 32.... What is the rule to get from one term to the next?

• add 2

• add 4

• multiply by 2

• multiply by 4

Given the sequence 2, 4, 8, 16, 32.... the common ratio is 2, so the sequence is:

• arithmetic

• linear

• geometric

• quadratic

Given the sequence 15, 12, 9, 6, 3.... the common difference is -3, so the sequence is:

• arithmetic

• 45

• 15

• 12

• 3
