<span>A geometric sequence is a sequence of
numbers where each term after the first is found by multiplying the
previous one by a fixed, non-zero number called the common ratio.
</span>The common ration is obtained by dividing the a term by the preceding term.
Given that f<span>our students wrote sequences during math class with
Andre writing
Brenda writing </span>
Camille writing
Doug writing
Notice that the common ratio for the four students is
.
For Andre, the last term is wrong and hence his sequence is not a geometric sequence.
For Brenda, the last term is wrong and hence her sequence is not a geometric sequence.
For Camille, her sequence is not a geometric sequence.
For Doug, his sequence is a geometric sequence with a common ratio of.
Therefore, Doug wrote a geometric sequence.
