What is the recursive rule for the sequence 2, -1, 1/2 , -1/4

Helga [31]

Answer:

$a_n=\frac{-1}{2}a_{n-1}$

$a_1=2$

Step-by-step explanation:

The recursive rule is a term defined in terms of other terms in the sequence.

The is a geometric sequence because it has a common ratio.

The common ratio can be found by dividing a term by previous term.

For example, all of these are equal:

$\frac{-1}{2}$

$\frac{\frac{1}{2}}{-1}$

$\frac{\frac{-1}{4}}{\frac{1}{2}}$

They are all equal to $\frac{-1}{2}$ .

So we are saying:

$\frac{\text{term}}{\text{previous term}}}=\frac{-1}{2}$

More formally:

$\frac{a_n}{a_{n-1}}=\frac{-1}{2}$ .

Multiply both sides by $a_{n-1}$ :

$a_n=\frac{-1}{2}a_{n-1}$

When doing recursive form, you need to state a term of the sequence (or more depending on the recursive form you have).

So the first term is 2.

So the full thing for the answer is:

$a_n=\frac{-1}{2}a_{n-1}$

$a_1=2$

Due to temporary tax cuts in 2010, persons in the U.S. who earned $50,000 per year had a lower tax rate. On average, these perso

seropon [69]

Answer:

extra money earn by typical person earning = $1850

Step-by-step explanation:

earned = $50,000 per year

retained = 2%

credit on their federal tax return = $850

amount of taxes = $850

typical person earning = $50,000

to find out

extra money did a typical person earning receive due to the tax cuts

solution

extra money earn by typical person earning is

extra money earn by typical person earning = 2% of $50000 + $850

extra money earn by typical person earning = $1000 + $850

extra money earn by typical person earning = $1850
