Answer:
a(4) = -17
Step-by-step explanation:
hello :
use : a(n) =a(n-1) -5
a(n) -a(n-1) = -5 (common differnce for arithmetic sequence)
the ni-eme term is : a(n) = a(1) +(n-1)d d = -5 and a(1) = -2
so : a(n) = -2 +(n-1)(-5)
a(n) = -5n+3
when : n= 4 a(4) = -5(4)+3 =-17

Answer:
Smallest number of rows that is needed to seat these people = 16
Step-by-step explanation:
Given - A theatre has seats arranged in rows of 24, three hundred eighty -two(382) people attend a show at the theatre.
To find - What is the smallest number of rows that is needed to seat these people?
Solution -
Given that,
Total number of seats in a Row = 24
Let us assume that, there are x rows
As.
There are 382 people in the Theatre
So,
Minimum seats required is
24 x = 382
⇒x = 382 ÷ 24
⇒x = 15.91
i.e.
Smallest number of rows that is needed to seat these people = 16
