In a music stadium, <em>35th </em>row has <em>120</em> seats
and explicit formula is <em> </em>is explicit formula for given sequence.
Step-by-step explanation:
In music stadium, there are 18 seats in first row and 21 seats in second row and it is continuously increasing by 3
Here, Arithmetic sequence is 18,21,24,27.....120
There Arithmetic sequence is given as a,a+d,a+d......a+(n-1)d
Where, a = First term = 18 and d = Increment = 3
Q (a) Write an explicit rule to model the sequence formed by the number of seats in each row.
Now, Create an explicit formula
<em> is explicit formula for given sequence.</em>
Q (b) Use the rule to determine which row has 120 seats.
Given
To determine which row has 120 seats.
Therefore, 35th row has 120 seats
