Which of the following is a geometric sequence? Question 11 options: A) 2, 6, 18, 54, 162, 486, ... B) 0, 5, 10, 15, 20, ... C) 1, 5, 9, 13, 17, ... D) 5, 1, –3, –7, –11, –15, ...
A geometric sequence is a sequence that increases by a factor from one term to the next. A is the only one that does this, and it increases by a factor of 3. All the others are an arithmetic sequence, where each term in increasing by a constant number.
