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 Seven Dimensions include Physical, Intellectual, Environmental, Vocational, Social, Emotional and Spiritual health
The pH shows the degree of acidity of alkalinity of a solution. The pH of the HF can be obtained from the ICE table.
<h3>What is pH?</h3>
The term pH refers to the hydrogen ion concentration of a solution. Recall that acids produce hydrogen or oxonium ion in solution.
The first step to determine the pH of the HF solution is to set up the ICE table as shown;
HF + H2O ⇄ H3O^+ + F^-
I
C
E
The values of the initial concentration of HF as well as the Ka of HF are not given. If these two values are give, the pH can be obtained from;
Ka = [H3O^+] [ F^-]/[HF] Knowing that [H3O^+] = [ F^-] = x
