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 =
15 + $32.50 + 8% = $51.30
15 + 32.50 = 47.50
8% × 47.50 = 3.80
47.50 + 3.80 = 51.30
