Answer:
Option (B)
Step-by-step explanation:
Given sequence is 45, 135, 405, 1215, 3645..........
Since it's a geometric sequence,
Common ratio of each successive term to the previous term
r = 
First term of the sequence 'a' = 45
Explicit formula of a geometric sequence will be,


Recursive formula of this sequence will be,
, 
Therefore, Option (B) will be the answer.
Answer: You should play if you are feeling better. Playing on an injured leg could injure it further. You also should see a doctor if it is that bad.
Step-by-step explanation:
12 multiplied by 12 equals 144.
X = the amount of water to add
10 - x = amount of 18% bleach to add
.18(10-x)= .12 x 10
1.8 -.18x =1.2
-.18x = -.6
x = 3 1/3 liters water
therefore 6 2/3 liters bleach
