Question

What is the common ratio in the sequence -6, -3, -3/2, 3/4

Answer 1

Well, think about what's happening from one number to the next. What do you do to -6 to get to -3? You divide by 2. Does the pattern continue? Yes, because the next number is 3/2. And since 2*2 is 4, the next number is 3/4. So your ratio is 1/2.
