Answer: neither

Step-by-step explanation:

Consider sequence a_1 , a_2 , a_3 , .....a_n, where n acn be any natural number.

This sequence is said to be Arithmetic sequence if the difference between two consecutive terms is equal.

i.e, if it is arithmetic then d=a_2-a_1=a_3-a_2=...=a_n-a_{n-1}

This sequence is said to be Geometric sequence if the common ratio between two consecutive terms is equal.

r=\dfrac{a_2}{a_1}=\dfrac{a_3}{a_2}=......=\dfrac{a_n}{a_{n-1}}}

The given sequence =  1, 2, 2, 3, ...

Here , 2-1\neq2-2 , so difference between two consecutive terms is not equal.

⇒ Its not an Arithmetic sequence.

Also , \dfrac{2}{1}\neq\dfrac{2}{2}\neq\dfrac{3}{2}, so ratio between two consecutive terms is also not equal.

⇒ Its not an Geometric sequence.

Hence, the given sequence is neither arithmetic nor geometric.

<h2>Hello!</h2>

The answer is: 50% (0.5)

<h2>Why?</h2>

Exponential growth equations are use to predict the growth (in function of time) using proportional information.

We can calculate the exponential growth using the following formula:

y=S(1+r)^{t}

Where,

S, is the starting value

r, is the growth rate

t, is the time

So, we are given the function:

f(t) = 3(1 + 0.5)^{nt}

Where,

f(t), is the function,

3, is the starting value (lb)

0.5 (50%) is the growth rate

nt, is the time elapsed.

Hence,

From the given function, we know that the growth rate is equal to 0.5, and it's equal to 50%.

We can turn the growth rate given in real numbers to percent value by multiplying by 100

GrowthRate(Percentage)=0.5*100=50(Percent)

So, the growth rate is 50%.

Have a nice day!
