Answer:

Correct answer is: D) a₆ = - 11

Step-by-step explanation:

Given:

a₁ = 9 and aₙ = aₙ₋₁ - 4

We know it is

a₆ = a₅ + d also it is given a₆ = a₅ - 4

When we equate the right sides of equality we get:

a₅ + d = a₅ - 4 => d = - 4

We also know it is a₆ = a₁ + 5 d

Now we will find a₆

a₆ = 9 + 5 (-4) = 9 - 20 = - 11

a₆ = - 11

Answer:

The discount points will cost 3749.

Step-by-step explanation:

The first monthly interest payment is $820.

So, annual interest paid = $820\times12$ = $9,840

Now, converting the annual interest to decimal = $\frac{9840}{0.105}$ = $93,714.28

As given, the bank requires 4 discount points, this becomes 0.04.

So, total loan amount = $93714.28\times0.04$ = $3748.57 ≈ $3749

Hence, the discount points will cost 3749.
