Question

PLEASE HELP ME!!

Answer 1

\[a_n=a_1+d(n-1)\]
where \(a_1\) is the first term (number of seats in first section)
d = number of seats added for each section

Answer 2

what is n?

Answer 3

n is the term number. It stays n for the general equation, but when you want to find the seats is a particular section, you'd substitute for it. For example when you want to find the seats in section 20, plug in 20 for n.

Answer 4

oh okay thank you!

Answer 5

you're welcome

Answer 6

In this case, you won't plug any value in for n. You'll leave it alone

so for instance, say you had 5+3(n-1), that would simplify to...


5+3(n-1)
5+3n-3
5-3+3n
2+3n
3n+2


This is just an example of course. It's not the final answer
