Answer:
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 <u>arithmetic progression</u>
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
<u>Verification</u>:-
substitute n = 14 , a=22 and d=6
