NEED HELP ASAP NO LINKSOn the first day it was posted online, a music video got 1500 views. The number of views that the video got each day increased by 18% per day. How many total views did the video get over the course of the first 27 days, to the nearest whole number?

the total number of views that the video got over the course of the first 27 days is 718833

Step-by-step explanation:

The number of views that the video got each day increased by 18% per day. It means that the number of views is increasing in geometric progression. The formula for determining the sum of n terms(days), Sn of a geometric sequence is expressed as

Sn = (ar^n - 1)/(r - 1)

Where

n represents the number of terms(days) in the sequence.

a represents the first term in the sequence.

r represents the common ratio.

From the information given,

a = 1500

r = 1 + 18/100 = 1.18

n = 27 days

Therefore, the sum of the first 27 terms, S27 is

S27 = (1500 × 1.18^(27) - 1)/1.18 - 1

S27 = (1500 × 86.26)/0.18

S27 = 718833

Hopefully It helps:)

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
