Answer:

S_{13} = 403

Step-by-step explanation:

the sum to n terms of an arithmetic series is

S_{n} = \frac{n}{2} (a + l) ← a is the first term and l the last term

here a = - 5 and l = 67 , then

S_{13} = \frac{13}{2} (- 5 + 67) = 6.5 × 62 = 403

Money is invested into an account earning 4.25% interest compounded annually. If the accumulated value after 18 years will be $2
Lunna [17]
We are given with the following:
Effective annual interest, i = 0.0425
Future worth, F = $25000
Number of years, n = 18

We use the formula to solve for the present worth of the money:
P = F / (1 + i)^n
P = 25000 / (1 + 0.0425)^18
P = 11818.73

The closest answer is:

The "divisor" in synthetic division is most conveniently the value of the zero of the binomial term. Here, that is x=5. You also need to make sure you include all of the coefficients in the "dividend", putting zero where terms are missing.

The appropriate choice is A.
