In order to solve for a nth term in an arithmetic sequence, we use the formula written as:
an = a1 + (n-1)d
where an is the nth term, a1 is the first value in the sequence, n is the term position and d is the common difference.
First, we need to calculate for d from the given values above.
<span>a1 = 38 and a17 = -74
</span>
an = a1 + (n-1)d
-74 = 38 + (17-1)d
d = -7
The 27th term is calculated as follows:
a27 = a1 + (n-1)d
a27= 38 + (27-1)(-7)
a27 = -144 -----------> OPTION D
Answer:
False
Step-by-step explanation:
A subset is a set whose elements belong to another set
If B is a subset of A, B would contain elements of A
For example, A = {a, b, c} and if B is a subset of A , B = { a, b}
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:
B. 9/26.
Step-by-step explanation:
You need to change the coefficient of x in the first equation to 9/13 so that adding the 2 equations would eliminate x.
So you would multiply by
= 9/13 / 2
= 9/13 * 1/2
= 9/26 (answer)
