Ainat [17]

Answer:

f(n) =320\times (1.25)^{n-1}

Step-by-step 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. = f(n) =f(1)\times r^{n-1}

So, nth term of the given situation :

f(n) =320\times (1.25)^{n-1}

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

So, the number of views Vera's video got on the nth day = 320\times (1.25)^{n-1}
