Answer:
Thus the last row has 119 seats.
The total number of seats in 24 rows = 1476
Step-by-step explanation:
The number of seats in each row make an arithmetic series. We will use arithmetic equation to find the number of seats in last row:
An = a1+ (n-1)d
An = 4+(24-1)5
An = 4 + (23)(5)
An = 4 + 115
An = 119
Thus the last row has 119 seats.
Now to find the sum of seats we will apply the formula:
Sn = n(a1 + an)/2
Sn = 24(4+119)/2
Sn = 24(123) /2
Sn = 1476 .....
The total number of seats in 24 rows = 1476....

Answer:Let's solve for a.
d=

5
a+h
Step 1: Flip the equation.
4
5
a+h=d
Step 2: Add -h to both sides.
4
5
a+h+−h=d+−h
4
5
a=d−h
Step 3: Divide both sides by 4/5.
