Question

Find the next three terms of the sequence. -4, -8, -16, -32,... A. -96, -288, -864 B. -64, -128, -256 C. -64, -288, -256 D. -36, -40, -44

Answer 1

Sequence given:

`-4,-8,-16,-32,...`

As we can see, the pattern is that a0 is multiplied by 2. Then a1 is multiplied by 2 and so on:

`-4*2=-8`
`-8*2=-16`
`-16*2=-32`

Therefore, the next three terms are:

`-32*2=-64`
`-64*2=-128`
`-128*2=-256`

Answer: B. -64, -128, -256
