Answer:
A,B, and C
Step-by-step explanation:
All of the answers are correct besides D, none of the above
An=Asub1(r)n-¹
=5(-2)7-¹
=5(64)
A7=320
Answer: v=-18/5
Step-by-step explanation:
Assuming you want to solve for v, we need to use our algebraic properties.
[subtract both sides by 2]
[multiply both sides by 3]

Now, we know that v=-18/5.
Hello
8y+y-5y = 9y- 5y =4y
or 8y+y-5y = y(8+1-5) =y (9-5) = y(4) =4y
Step-by-step explanation:
Since the sequence above is an arithmetic sequence
For an nth term in an arithmetic sequence
A(n) = a + ( n - 1)d
where a is the first term
n is the number of terms
d is the common difference
From the question
a = 1/3
d = 1/2 - 1/3 = 1/6 or 2/3 - 1/2 = 1/6
Substitute the values into the above formula
That's
<h3>

</h3>
So the nth term of the sequence is
<h3>

</h3>
For a50 since we are finding the 50th term
n = 50
So we have
<h3>

</h3>
We have the final answer as
<h3>

</h3>
Hope this helps you
