Find the explicit formula for the nth term of the 2/9,0,2/9,0,......

nexus9112 [7]

The odd-numbered terms are $\dfrac19+\dfrac19$ , while the even-numbered terms are $\dfrac19-\dfrac19$ , so one formula for the sequence is

$a_n=\dfrac19\left(1+(-1)^{n+1}\right)$

where $n\ge1$ .

P=$222 r=12% Y=10 A=?

sergey [27]

To solve for the A or the principal amount plus interest you can use two formulas:

A = P + I

Where: P = Principal
I = Interest

or you can use

A = P (1+ rt)

Where: P = principal
r = rate in decimal
t = time in years

With your given you can use the second one, without having to use the first.
Given that the Principal amount is $222 and the rate is 12% and time is 10 years, we first need to convert your rate into decimal by dividing the value in percent by 100 which will yield 0.12.

Then now we can just input the data that you know into the formula:
A = P(1+ rt)
= $222(1 + (0.12)(10))
= $222(2.2)
= $488.40

Your A is then equal to $488.40

If you need to get the simple interest all you need to use is the first formula given:

A = P + I
for the interest you transpose the P to the side of the A and you will get:
I = A - P
= $488.40 - $222
= $266.40

$266.40 is the added interest to the principal amount.

The mean increases by 3.

Step-by-step explanation:

What's an outlier?

An outlier is a data point that's very different from the other data points. In this example, the outlier is 50, as the other data points are around the number 80.
