What are the first terms of the sequence

allsm [11]

Answer:

First five terms are:

4300, 4240, 4180, 4120, 4060

Step-by-step explanation:

Minus 60 from the predicted number of cars in the first month to get the second month, then do the same for the predicted number of cars in the second month to get the third month and so on.

The expression for the nth term would be = 4300 - (n-1)(60)

= 4360 - 60n

How much must be deposited today into the following account in order to have $35,000 in 7 years for a down payment on a house?

Rom4ik [11]

Answer:

The amount that must be deposited is $ 19973.87.

Step-by-step explanation:

We have a relation between future value present value as:

F= P $(1 +\frac{r}{n} )^{nt}$

F=future value

P=present value

r=rate (as a decimal)

n=number of compounding periods per year

t=number of years

Now,

assume rate as 8%

35000= P $(1+\frac{0.08}{12} )^{12*7}$

or, 35000= P × $1.0067^{84}$

or, P = $\frac{35000}{1.7522}$

or, P = $ 19973.87

So you must deposit $ 19973.87 today.
