D) The population alternates between increasing and decreasing
we have
Find the value of
For n=2
Find the value of
For n=3
For n=4
For n=5
therefore
The population alternates between increasing and decreasing
Answer:

Step-by-step explanation:
3a-4≤5
A) G=6E
B) G=2E+3
C) E=3G+2
D) G=3G+2
Answer
The equation shows this situation is Option (B) .
i.e G=2E+3
Reason
As given
Gary is 3 years older than twice the age of his sister (Elena) .
Let us assume that the age of the Gary be G.
Let us assume that the age of the Elena be E.
Than the equation becomes
E = 2G + 3
Therefore option (B) is correct .
The first thing we must do for this case is to define variables.
We have then:
G: Gary's age
E: Elena's age
We then have the following expression:
Gary is 3 years older than twice the age of his sister (Elena):
Using the defined variables, we can write the expression as:
G = 2E + 3
Answer:
an equation for this situation is:
B) G = 2E + 3
