Answer:
Below in bold.
Step-by-step explanation:
Nth term an = a1 + d(n - 1) where a1 = term 1 and d = common difference.
Here a1 = 5 and d = 8-5 = 3.
So an = 5 + 3(n - 1)
15th term a15
= 5 + 3(15 - 1)
= 5 + 42
= 47.
Her IRA interest at the end of 30 years is mathematically given as
Interest= 438,765.56
<h3> IRA interest </h3>
Question Parameters:
- N = 30
- PV = 0
- rate = 5%
- FV = 800,000
Generally the equation for the payment function on excel is mathematically given as
A=PMT(rate, nper, pv, [fv], [type])
Therefore, inputting our functions
A=PMT(rate, nper, pv, [fv], [type])
where
A=PMT(5%, 30, 0, [800000], [])
A = 12,041.1481
Hence
interest = 800,000 - 30*12,041.1481
Interest= 438,765.56

The appropriate descriptors of geometric sequences are ...
... B) Geometric sequences have a common ratio between terms.
... D) Geometric sequences are restricted to the domain of natural numbers.
_____
The sequences may increase, decrease, or alternate between increasing and decreasing.
If the first term is zero, then all terms are zero—not a very interesting sequence. Since division by zero is undefined, the common ration of such a sequence would be undefined.
There are some sequences that have a common difference between particular pairs of terms. However, a sequence that has the same difference between all adjacent pairs of terms is called an <em>arithmetic sequence</em>, not a geometric sequence.
Any sequence has terms numbered by the counting numbers: term 1, term 2, term 3, and so on. Hence the domain is those natural numbers. The relation describing a geometric sequence is an exponential relation. It can be evaluated for values of the independent variable that are not natural numbers, but now we're talking exponential function, not geometric sequence.
Quadrant Four (IV) since the x coordinate is a positive and the y coordinate is a negative.
