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

train traveling with 100 cars all cars are exact size. the cars are 20 ft long 10ft wide and 10ft tall. how much available volum
jeyben [28]

Find the volume of 1 car by multiplying the length by the width by the height:

Volume of 1 car = 20 x 10 x 10 = 2000 cubic feet.


Now multiply the volume of 1 car by the total number of cars:

2000 x 100 = 200,000 cubic feet total.

Please help with the question,
castortr0y [4]
The correct answer is x^2-2x+2=0

 The explanation is shown below:

 1. To solve the problem shown in the figure above, you must apply the following proccedure:

 2. You have that the roots of the quadratic equation shown in the figure attached in the problem are:

  x=-1±i

 3.  Then, you know the quadratic formula to solve quadratic equations, which is:

 (-b±√(b^2-4ac))/2a

 4. You can see in the figure that a=1 and c=2; then, by analizing this, you can conclude that the coefficient b is:

 b=-2

 5. Therefore, you can conclude tha the quadratic equation is:

 x^2-2x+2=0

 6. If you want to verify it, apply the quadratic formula to the quadratic equation shown above and you will obtain the roots shown in the figure.

Length of rectangle

Rectangle 1) 23m
Rectangle 2) 14yd

Width of rectangle

Rectangle 1) 36m
Rectangle 2) 3.5yd

An expressions is an equations but without the equal sign ( = ) and without the solution ( the answer)

The formula To find the area of a rectangle is

A = base * height
or
A = length * width

Rectangle’s area written in as an expression

Rectangle 1) 23 * 36
Rectangle 2) 14 * 3.5

To find the area, you multiply the numbers

23 * 36 = 828
14 * 3.5 = 49

Rectangle’s area written as a number

Rectangle 1) 828m
Rectangle 2) 49yd
