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\times2=-8$$-8\times2=-16$$-16\times2=-32$

Therefore, the next three terms are:

$-32\times2=-64$$-64\times2=-128$$-128\times2=-256$

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