Answer:
its none of these answers ;-;
Step-by-step explanation:
3^2 + 8 ÷ 2 - (4 + 3)
we do what's in parentheses first. (pemdas)
so now we have, 3^2 + 8 ÷ 2 - 7
next exponents, 3^2=9
9 + 8 ÷ 2 - 7
next division, 8÷2=4
9 + 4 - 7
next addition, 9+4=13
13-7
finally subtraction, 13-7=6
final answer: 6
The equation for the nth term in the arithmetic sequence is 8n + 8.
The number of people that can be accommodated in the 16th row is 136.
<h3>What is an
arithmetic progression?</h3>
Arithmetic Progression (AP) is a sequence of numbers in order, in which the difference between any two consecutive numbers is a constant value. It is also called Arithmetic Sequence.
Given that,
No. of seats in first row = 16
No. of seats in second row = 24
No. of seats in third row = 32
Total number of rows = 50
It forms an arithmetic progression
First term = a = 16
common difference d = 8
Number of terms, n = 50
(A) The formula for the n th term of an arithmetic progression is given by
Tn = a + (n - 1) d
= 16 + (n-1) 8
= 16 + 8n - 8
Tn = 8n + 8
(B) Now,
n = 16
The number of seats in 16 th row is given by
T(16) = 8 x 16 + 8
T(16) = 136 seats
Hence, (A)The equation for the nth term in the arithmetic sequence is 8n + 8. and (B) The number of people that can be accommodated in the 16th row is 136.
