An arithmetic sequence (a_n) is as follows:
where
is the first term and d is the constant difference,
thus, we see that the n'th term of an arithmetic sequence is
in our particular case d=5, the third term is 8, so we have:
and the general term is
,
Answer: first term is -2, n'th term is -2+5(n-1)
Informally assess the degree of visual overlap of two numerical data distributions with similar variabilities, measuring the difference between the centers by expressing it as a multiple of a measure of variability.

Answer:
<em>The expression is equal to 22</em>
Step-by-step explanation:
<u>Expression Evaluation</u>
We are given the expression
10 + 2p - 3r
And it's required to evaluate it when p=3 and r=2. This means we have to replace the letter for the value assigned to them, as follows:
10 + 2*3 - 3*(-2) = 10 + 6 - (-6)
= 10 + 6 + 6
= 22
The expression is equal to 22
Answer:
2472 students
Step-by-step explanation:
<u>What we know:</u>
- There are 6 schools
- Each school has 412 students
<u>What we're trying to solve:</u>
How many students are there altogether?
To find this, we multiply 412 by 6. Doing this is essentially the same as adding 412 to itself 6 times for each school there is in the district.
412 students × 6 schools
= 2472 students
Therefore, there are 2472 students in the district.
I hope this helps!
