Question

An investor deposits $2,000 in an account that earns 3.4% interest compounded quarterly. The balance in the account after $n$ quarters is given by $A_n = 2,000(1 + frac{0.034}{4})^n$, $n = 1, 2, 3, ...$ (a) Write the first eight terms of the sequence. (Round your answers to the nearest cent.) $A_1 = $ $A_2 = $ $A_3 = $ $A_4 = $ $A_5 = $ $A_6 = $ $A_7 = $ $A_8 = $ (b) Find the balance in the account after 5 years by computing the 20th term of the sequence. (Round your answer to the nearest cent.) $A_{20} = $ (c) Is the balance after 20 years twice the balance after 10 years? Explain. Yes, because interest is not paid until the end of the investment period. No, because the interest rate will increase or decrease over time. No, because the value of the investment does not increase linearly. No, because rounding errors cause the balances to vary slightly over time. Yes, because interest is accrued at a fixed rate per year.
