A student wrote a list of six consecutive integers. If the sum of the first integer and sixth integer is 1, which integer is the least of the six integers?
A. -2
B. 1
C. 3
D. 5
Answer:
A
Step-by-step explanation:
The student wrote a list of six consecutive integers.
The sum of the first integer and the sixth is 1.
Let the first integer be represented by n.
Then the subsequent integer will be (n + 1).
Therefore, our sequence is:
n, n + 1, n + 2, n + 3, n + 4, and n + 5.
The sum of the first and sixth is 1. Therefore:
[tex](n)+(n+5)=1[/tex]
Solve for n. Combine like terms:
[tex]2n+5=1[/tex]
Thus:
[tex]2n=-4[/tex]
And:
[tex]n=-2[/tex]
Thus, our first term is -2.
Therefore, our sequence is:
-2, -1, 0, 1, 2, 3
The least of the six integers is -2.
Our answer is A.
Answer:
A

What are the first five terms of the sequence represented by the explicit equation g(n) = 34 - 5n ?
Answer:
Step-by-step explanation:
Remark
My guess is that what is confusing you is not what you have to do, but why it is disguised as g(n)
What you are doing in effect is setting up a table. You are also not certain where the table starts. And that is a problem. I will start it at zero, but it might be 1.
zero
n = 0
g(0) = 34 - 5*0
g(0) = 34
One
n = 1
g(1) = 34 - 5*1
g(1) = 34 - 5
g(1) = 29
Two
g(2) = 34 - 5*2
g(2) = 34 - 10
g(2) = 24
Three
g(3) = 34 - 5*3
g(3) = 34 - 15
g(3) = 19
Four
g(4) = 34 - 5*4
g(4) = 34 - 20
g(4) = 19
Answer
0 1 2 3 4
34 29 24 19 14

You invest $4000 into an account that compounds interest on a quarterly basis at 3%. how much money will you have after 5 years? Compound interest formula: A = P(1+r/n)^(nt)
Answer:
26666.6
Step-by-step explanation:
So sorry if this is wrong i tried
The amount after 5 years is $4,644.74.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P[tex](1 + r/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
P = $4000
n = 4
r = 3%
t = 5 years
A = 4000 [tex](1 + 0.03/4)^{20}[/tex]
A = 4000 x [tex]1.0075^{20}[/tex]
A = $4,644.74
Thus,
The amount after 5 years is $4,644.74.

Elian and Alberto won tickets at a arcade. When they put their tickets together they had exactly 100. Alberto won 10 tickets less then Elian. Let A be the number of tickets Alberto won and e be the number of tickets Elian won.
Answer: See explanation
Step-by-step explanation:
Number of tickets Elian won = e
Number of tickets Alberto won = A = e - 10
Therefore, Elian + Alberto ticket = 100
e + (e - 10) = 100
2e - 10 = 100
2e = 100 + 10
2e = 110.
e = 110/2
e = 55
Elina has 55 tickets
Alberto has 55-10 = 45 tickets
