Answer:

The sequence is arithmetic

we know that

In an arithmetic sequence, the difference between consecutive terms is always the same and is called common difference

In this problem we have

3,9,15,21,...

Let

a1=3, a2=9,a3=15,a4=21

a4-a3=21-15=6

You invested $7,000 into a money market account for 10 years at an annual interest rate of 3%. How much is the accrued interest?
steposvetlana [31]

The total interest accrued is $2,407.41 if you invested $7,000 into a money market account for 10 years at an annual interest rate of 3%.

<h3>What is invested amount?</h3>

An investment is a payment made to acquire the securities of other firms with the intention of making a profit.

We are assuming the interest will be compounded annually

\rm A = P(1+\dfrac{r}{n})^{nt}

Where A = Final amount

          P = Principal amount

          r  = annual rate of interest

          n = how many times interest is compounded per year

          t = How long the money is deposited or borrowed (in years)

We have:

P = $7000

r = 3% = 0.03

t = 10 years

n = 1

\rm A = 7000(1+\dfrac{0.03}{1})^{1\times10}

After calculating:

A = $9407.41

I = A - P = 9407.41 - 7000 = $2,407.41

Thus, the total interest accrued is $2,407.41 if you invested $7,000 into a money market account for 10 years at an annual interest rate of 3%.
