Step-by-step explanation:
(2xS)+5=D
D+S=23
Answer:
a(n) = 

Step-by-step explanation:
The given expression is in the form of the explicit formula of a geometric sequence.
f(n) = 
Where 'a' = First term of the sequence
r = common ratio
Recursive formula of a geometric sequence is,
a(n) = 
a(n) = 
Where, 
So the recursive formula will be a(n) = 
No; just because there is a correlation does not prove causation.
The correlation says that as the amount of rainfall increases, the amount of oranges produced increases as well. It does not state what causes it.
