Question

Vera uploaded a hilarious video of a squirrel to a funny video website. It was viewed 320 times on the first day. Each day since then, the number of views was 25% more than the day before.

Let f(n) be the number of views Vera's video for on the nth day side she uploaded it.

What kind of sequence is it?
A. Arithmetic sequence
B. Geometric Sequence

Write an explicit formula for the sequence.
f(n)=

Answer 1

Explanation:

On first day , the video was viewed = 320 times .

We are given that Each day since then, the number of views was 25% more than the day before. This means the likes are increasing 1.25 per day .

So, this situation forms G.P.

Where common ratio r = 1.25

First term = f(1) = 320

Formula of nth term in G.P. =

So, nth term of the given situation :

Where f(n) denotes the number of views on nth day .

So, the number of views Vera's video got on the nth day =
