Answer:
74
Explanation:
28+2*(24-1)= 74
Given:- There are 28 seats in the front row of theater
Number of rows=24
To find:- The number of seats in the last row.
Use the formula to find the 24th term of this sequence.
Also each successive row has two more seats. This difference is same for the whole theater.
So, this forms an arithmetic sequence.
a1=21
D=2
We need to find number of seats in 24th row; which is given by a24
We use the formula for it
The length of the segment is an illustration of intersecting chords
The value of x is x = 27/14
<h3>How to determine the length of the segment?</h3>From the complete question (see attachment), we have:
AD = 12
AE = 3
BE = 14
EC = x
Start by calculating the length of ED
ED = AD - AE
This gives
ED =12 - 3
ED =9
The value of x is then calculated as:
x * BE = AE * ED
Substitute known values
x * 14 = 3 * 9
Evaluate the product
x * 14 = 27
Divide both sides by 14
x = 27/14
Hence, the value of x is x = 27/14
