<h2>Ans 2</h2>
Step-by-step explanation:
The above sequence is a geometric sequence
For an nth term in a geometric sequence
![a(n) = a ({r})^{n - 1}](https://tex.z-dn.net/?f=%20a%28n%29%20%3D%20a%20%28%7Br%7D%29%5E%7Bn%20-%201%7D%20)
where
n is the number of terms
a is the first term
r is the common ratio
From the question
a = 5
r = 10/5 = 2
Therefore the explicit formula for this sequence is
![a(n) = 5( {2})^{n - 1}](https://tex.z-dn.net/?f=a%28n%29%20%3D%205%28%20%7B2%7D%29%5E%7Bn%20-%201%7D%20)

Answer:
-1.8, -2.1, -2.5, -2.7
Step-by-step explanation:
the bigger the negative number, the smaller it is
Answer:
324
Step-by-step explanation:
One case has 9 boxes.
One box has 36 chocolates.
This equation would answer the amount in a case, case = chocolate*boxes
So there would be 36*9 chocolates, and that equals 324 in one case
f(x) = -10
set the equation equal to -10 and solve for x:
-10 = -x-1
Add 1 to both sides:
-9 = -x
Divide both sides by -1:
x = 9
