1. In an auditorium, there are 22 seats in the first row and 28 seats in the second row. The number of seats in a

row continues to increase by 6 with each additional row.

(a) Write an iterative rule to model the sequence formed by the number of seats in each row. Show your

work.

(b) Use the rule to determine which row has 100 seats. Show your work.

a) The sequence is 22 , 28 , 34, 40 ,46 , …..

b) The 14 term of the sequence has 100 seats

Step-by-step explanation:

In an auditorium, there are 22 seats in the first row and 28 seats in the second row,...

The sequence is 22 , 28 , 34, 40 ,46 , …..

we observe that the difference between 28 and 22 is '6'

between 34 and 28 is '6'

between 40 and 34 is '6'  and so on

The given sequence is arithmetic progression

Here d = 6 , a= 22

The 'n' th term of the sequence

b) Given and find n =?

n = 14

The 14 t h row has 100 seats

Verification:-

substitute n = 14 , a=22 and d=6

(I WILL PROVIDE A PIC OF TABLE FOR BETTER UNDERSTANDING)

A)(r-1)

B(r – 1)

100 = 22 + 6(r – 1)  

100 = 22 + 6r – 6  

100 = 16 + 6r  

r = 14

Also plz leave a thanks and a good rating! Would be appreciated! :)

answer: 26

step-by-step explanation:

well, michelle wanted to measure the height of her school's flagpole she placed a mirror on the ground 48 feet from the flagpole then walk backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft from the mirror using similar triangles find the height of the flagpole to the nearest tenth of a foot find the geometric mean of them pair of numbers. its easy math

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.

,, add !
