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

<h3>What is an
exponential function?</h3>
An exponential function is in the form:
y = abˣ
Where y, x are variables, a is the initial value of y and b is the multiplication factor.

The prediction about the waves if they were to crash into each other is that The resulting wave would travel at 4.2 hertz.
<h3>What is the wave about?</h3>
Note that:
Constructive interference of the waves is one that leads to an increase in amplitude or frequency of any kind of waves.
Hence:
F' = 3 Hz + 1.2 Hz
= 4.2 Hz
Destructive interference of the waves is one that lowers the amplitude or frequency of waves and as such:
F' = 3 Hz - 1.2Hz = 1.8 Hz
The prediction about the waves if they were to crash into each other is that The resulting wave would travel at 4.2 hertz.
