Use inductive reasoning to describe the pattern. Then find the next two numbers in the pattern.

–3, 9, –27, 81, . . .

subtract 12 from the previous term; –243, 729
multiply the previous term by 3; 243, 729
multiply the previous term by –3; –243, 729

-3 to 9 = multiply by -3
9 to -27 = multiply by  -3
-27 to 81 = multiply by -3
next to numbers are:
81 x -3 = -243
-243 x -3 = 729

anonymous · Answer

Choice A.
Does -3 - 12 = 9? Does 9 - 12 = -27?

Choice B. 
Does -3 x 3 = 9 and does 9 x 3 = -27?

Choice C.
Does -3 x -3 = 9 and does 9 x 3 = -27?

Choice D.
Does -3 + 12 = 9 and does 9 + 12 =-27??
