The rate is -3 because 4 * -3 = 12 and -12 and -12 * -3 = 36 etc.
Answer: C.
The first number is a positive 4, which is your a1. Then the geometric sequence goes to a negative implying that it is multiplied by a negative. So the a1 = 4 and it is being multiplied by a negative 3.
Answer:

5x5.50=27.5
x = xi + delta x
-2+1 = -1
y = yi + delta y
-5+3 = -2
