Question

The first three terms of a geometric sequence are as follows.

-3, 6, -12
Find the next two terms of this sequence.
Give exact values (not decimal approximations).

Answer 1

24, -48

Explanation:

In this geometric sequence, the previous number is being multiplyed by -2 each time

This said the next number is 24.

-12*-2=24

and the next one is -48.

24*-2=-48
