Answer:
a. -3
b. 324, -972, and 2,916
Step-by-step explanation:
a. Common ratio:
-108/36 = -3
36/-12 = -3
-12/4 = -3
Therefore, the common ratio = -3
b. To get the next three terms, multiply the each consecutive term by the common ratio.
Thus:
-108 × -3 = 324
324 × -3 = -972
-972 × -3 = 2,916
Therefore, the next three terms of the sequence are:
324, -972, and 2,916
