Write a recursive formula for the following arithmetic sequence. 8, 5, 2, −1,

1 answer:

8 0

Answer:

$a_{n}$ = $a_{n-1}$ - 3

Step-by-step explanation:

A recursive formula allows a term in the sequence to be found from the previous term by adding the common difference to it.

Here d = 5 - 8 = - 3, thus

$a_{n}$ = $a_{n-1}$ - 3 with a₁ = 8 ← recursive formula

Let N be no. of nickles. Then N($.05)+3N($.10)+2N($.25)=$3.40.

Or

4 nickels = $0.20
12 dimes = $1.20
8 Quarters = $2.00

Total = $3.40

Because the 0.96 is less than 1, it means that the house loses value over the years.

Convert 0.96 to a percent: 0.96 = 96%

100% - 96% = 4%

The house loses 4% of it's value every year.

Answer:

Infinite number of solutions

Step-by-step explanation:

$2(3 + 4x) = 8x + 6\\6 + 8x = 8x+6\\8x-8x=6-6\\0=0$

For any value of x, both equations are equal to each other because both sides are identical
