Ill give brainliest to right answer Find the common ratio of the geometric sequence -13, 39, -117,...−13,39,−117,...

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

F(2) = 0f(-2) = 0due to the way the equation is, answers with 0 are correct.
