Find the sum of the arithmetic series given a1
12, d = 4, and n = 30.
A. 8434
B. 4200
C.4216
D. 2100
Answer:
D
Step-by-step explanation:
The sum to n terms of an arithmetic series is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 12, d = 4 and n = 30 , then
[tex]S_{30}[/tex] = [tex]\frac{30}{2}[/tex] [ (2 × 12) + (29 × 4) ]
= 15(24 + 116)
= 15 × 140
= 2100 → D
The sum of the arithmetic series given a₁ =12, d = 4, and n = 30 is 2100, therefore the correct answer is D.
What is the Sum of arithmetic series?The sum of n terms of an arithmetic series can be easily found using a simple formula which says that, if we have an arithmetic series whose first term is a and the common difference is d, then the formula of the sum of n terms of the arithmetic series is as follows
Sn = n/2 [2a₁ + (n-1)d].
as given in the problem
a₁ =12, d = 4, and n = 30
Sn = 30/2 [2×12 + (30-1)×4]
= 2100
The sum of the arithmetic series given a₁ =12, d = 4, and n = 30 is 2100.

Lauren invests money in an account paying simple interest. She invests $50 and no money is added or removed from the investment. After one year, she has $50.50. What is the simple percent interest per year?
Based on the amount invested and the amount it grew to, the simple interest rate is 1%.
Lauren invested $50 and got $50.50 after a year.
What is the Simple Interest rate?This rate can be found by the formula:
= (Difference in investment in year 1) / Amount invested x 100%
Solving gives:
= (50.50 - 50) / 50 x 100%
= 1%
In conclusion, the rate is 1%.

If n + 7 = 10, evaluate 2n - 2
O 3
0 17
4
6
Answer:
The value of 2n - 2 is 4.
Step-by-step explanation:
Given the equation
[tex]n + 7 = 10[/tex]
Subtract 7 from both sides of the equation
[tex]n+7-7=10-7[/tex]
Simplify
[tex]n=3[/tex]
Now substituting n = 3 in the equation
2n - 2 = 2(3) - 2
= 6 - 2
= 4
Therefore, the value of 2n - 2 is 4.
