The n-th term a[n] is given by
.. a[n] = 4*(-5)^(n -1)
Then
.. a[7] = 4*(-5)^6 = 62,500
The 3rd selection is appropriate.

Answer:
a=c
Step-by-step explanation:

Answer:
20 % decay
Step-by-step explanation:
Exponential equations are in the form
y = a * b^x
a is the initial value
b is the growth or decay
b>1 is growth b-1 rate of growth
b <1 decay 1-b rate of decay
1-.8 = .2
Change to decimal form
20 % decay
