Question

What is the 8th term of this sequence?

Answer 1

Find the rate of change. -12/-3=4. 4 is the rate of change. Now that we have -192 as the 4th term, the simple way is to multiply it by 4 four times to get C, -49,152.

The equation for this would be -192(4)^4

Answer 2

You are multiplying by 4 each time.

1) -3 x 4 = -12

2) -12 x 4 = -48

3) -48 x 4 = -192

4) -192 x 4 = -768

5) -768 x 4 = -3072

6) -3072 x 4 = -12288

7) -12288 x 4 = - 49152

8) -12288 x 4 = -196608
