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) =
Answer:
The population will be 240,116
Step-by-step explanation:
Exponential growth can be represented by the expression:
where:
is the population at time (t)
is the initial value of the population
"r" is the annual rate of growth (written in decimal form)
and "t" is the time in years.
Therefore in this situation, P(16) is what we want to find [the population after 16 years]
the initial population is 110,000
the rate of growth is 0.05 [decimal form of 5%]
and t is 16 years.
Replacing all these in the given functional form gives:
