Answer:
Step-by-step explanation:
In a geometric sequence, consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as 
an = a1r^(n - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
From the given sequence, 
a1 = - 5
r = 15/- 5 = - 3
Therefore, the explicit rule for this sequence is 
an = - 5(- 3)^n - 1

Step-by-step explanation:
<u>Step 1: Define</u>
-5x - 1 ≤ -9
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 1 to both sides:                    -5x ≤ -8
- Divide -5 on both sides:             x ≥ 8/5
Here we see that any value <em>x</em> greater than or equal to 1.6 would work as a solution.
Therefore, our answer is A. 1, as it doesn't work as a solution.
