Sn=A1(1-r^n)/(1-r)
Sum of a finite geometric series formula
We know the sum, number of terms and rate, so you plug those in.
-255=A1(1-(-4)^4))/(1-(-4)
-255=A1(1-256)/5
-255=A1(-255)/5
-1275=A1(-255)
5=A1
Hope this helped! Let me know if you have any questions.
Answer:

Answer:
19
Step-by-step explanation:
20 - 8 = 12

i subtracted.
Heeelllllloooooo! :D
Okay this is a very similar question to the one I answered earlier....
I'll show you step by step so you will be able to do this in the future on your own
(y - y₁) = m(x - x₁) -----> point-slope form
(y + 6) = (-0.38)(x - 5)
y + 6 = -0.38x + 1.9
<u>y = -0.38x - 4.1</u><u />
There you go!
