People who ask questions and need our help. You know some people answer for points. They just want points and don't give us the correct answers. I asked a question twice, and people just wanted the points. ARE WE GOING TO LET THEM DO THIS. This website is for people who need help. Some people do ask questions bc they dont want the points, and people answer it. I'm not talking about them. Im talking about when someone really needs our help. If this question gets deleted, ill make another one, and another one. Try to stop me. But this is unfair. And i will protest until i die SPAM WITH US!

Period queen

Step-by-step explanation:

perio you telle

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

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 ☺
