Four students wrote sequences during math class.

andre - 3/4, 3/8, - 3/16, - 3/32..
brenda 3/5, -3 /8, 3/16, 3/32..
camille 3/4, 3/8, - 3/16, - 3/32..
doug 3/4, - 3/8, 3/16, -3 /32..

which student wrote a geometric sequence?
andrea
brenda
camille
doug

Doug wrote geometric sequence.

Step-by-step explanation:

a geometric sequence is where we get common ratio between consecutive terms

In case of Andre:

On substituting the values so as to find common ratio is

Andre did not write a geometric sequence.

In case of Brenda:

On substituting the values so as to find common ratio is

Brenda did not write a geometric sequence.

In case of Camille

On substituting the values so as to find common ratio is

Camille did not write a geometric sequence.

In case of Doug:

On substituting the values so as to find common ratio is

Doug wrote a geometric sequence.
