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

A baseball infield is a square, each side measuring 90 feet. To the nearest foot, what is the distance from home plate to second
suter [353]

Using the Pythagorean theorem:

90^2 +90^2 = X^2

8100 + 8100 = x^2

16,200 = x^2

X = √16,200

X = 127.28 feet.

Rounded to the nearest foot = 127 feet.

Three ordered pairs that solve the equation x - 4 Y equals -18
lawyer [7]
X-4y=-18
an easy way is to solve for oone variable
solve for x
add 4y both sides
x=4y-18

when y=1, x=-16
when y=0, x=-18
when y=2, x=-10

(x,y)
so some orderd pairs are
(-16,1)
(-18,0)
(-10,2)

Use the function rule to complete the table.<br> -10x+y=4<br><br> X: -2 -1 0 1 2 <br> Y:
harina [27]
Y = 10x + 4
 x                      y
-2  10(-2)+4 = -16
-1  10(-1)+4 = -6
0    10(0)+4 = 4
1    10(1)+4  = 14
2    10(2)+4 = 24
