F(5) = - 2f(4) + 1
f(4) = -2f(3) + 1
f(3) = -2f(2) + 1
f(2) = -2f(1) + 1
Therefore:
 f(2) = -2(3) + 1 = -5
f(3) = -2(-5) + 1 = 11
f(4) = -2(11) + 1 = -21
Therefore f(5) = -2(-21) + 1 = 43

Euler Bank advertises that it compounds interest continuously and that it will double your money in 20 yr. What is the annual in
Romashka [77]

To solve this problem you must apply the proccedure shown below:

1. You must apply the following formula:

FV=(PV)(e^{it})

Where FV is the future value, PV is the present value, i is the interest rate and t is the time in years.

2. You have that the bank will double your money in 20 years. Therefore:

FV=2PV

3. Substitute values into the formula and solve for i, as following:

2PV=(PV)(e^{(i)(20)} \\ 2=e^{(i)(20)}

4. By applying natural logarithm, you have:

 ln(2)=(i)(20) \\ i= \frac{ln(2)}{20}  \\ i=0.0346

 i=3.46 %

 The answer is: 3.46 %
