ANSWER
Frequency=2
Midline =3
Amplitude =5
Period =π
EXPLANATION
We have:

The given function is of the form;

where
a=|5| =5 is the amplitude
and b=2 is the frequency.
and 2π/b=2π/2=π
The range of the given function is
8≤y≤-2
The midline is

For geometric sequence, you multiply the common ratio to the previous one.
120 × (-1/2) = -60
-60 × (-1/2) = 30
30 × (-1/2) = -15
So your first three terms is
-60 , 30 , -15
