Answer:
The common ratio is -2
Step-by-step explanation:
Why? How?
Well you'd have to divide or multiy in a geometric sequence.
So, moving from -11 to 22 is 22 divided by -11 giving -2. The next term, the forth term, is 22 × -2 that is -44. the first term would be, moving down, -11 ÷ -2 which is 5.5.
All terms together: 5.5, -11, 22, -44, 88, -176
Hope you get it right and good luck.
