2,-10,50,-250,.. Geometric sequence

nikklg [1K]

This question is incomplete, here is the complete question

What is the recursive formula for this geometric sequence 2, -10, 50, -250, .... ?

The recursive formula for this geometric sequence is:

$a_{1}$ = 2; $a_{n}$ = (-5) • $a_{n-1}$

Step-by-step explanation:

To find the recursive formula for a geometric sequence:

Determine if the sequence is geometric (Do you multiply, or divide, the same amount from one term to the next?)
Find the common ratio. (The number you multiply or divide.)
Create a recursive formula by stating the first term, and then stating the formula to be the common ratio times the previous term.

The recursive formula is:

$a_{1}$ = first term; $a_{n}$ = r • $a_{n-1}$ , where

$a_{1}$ is the first term in the sequence
$a_{n-1}$ is the term before the nth term
r is the common ratio

∵ The geometric sequence is 2 , -10 , 50 , -250

∴ $a_{1}$ = 2

- To find r divide the 2nd term by the first term

∵ $r=\frac{a_{2}}{a_{1}}$

∴ $r=\frac{-10}{2}=-5$

- Substitute the values of $a_{1}$ and r in the formula above

∴ $a_{1}$ = 2; $a_{n}$ = (-5) • $a_{n-1}$

The recursive formula for this geometric sequence is:

$a_{1}$ = 2; $a_{n}$ = (-5) • $a_{n-1}$

Find the mean, median, mode, range, and standard deviation of the data set obtained after multiplying each value by 2. Round to

Elena L [17]

Answer:

mean: 8.9, median: 9, mode: 3, range: 14, standard deviation: 5.1

Step-by-step explanation:

The mean is all the numbers added up, divided by how many numbers there are. To get the median you arrange the numbers biggest to smallest and find the middle number.

A person has utility function u(x, y) = 100xy + x + 2y. Suppose that the price per unit of x is $2, and that the price per unit

Kazeer [188]

Answer:

x = 250

y = 125

u(x,y) = 3125500

Step-by-step explanation:

As given,

The utility function u(x, y) = 100xy + x + 2y

$P_{x}$ = 2 , $P_{y}$ = 4

Now,

Budget constraint -

$P_{x}$ x + $P_{y}$ y = 1000

⇒2x + 4y = 1000

So,

Let v(x, y) = 2x + 4y - 1000

Now,

By Lagrange Multiplier

Δu = Δv

⇒< 100y + 1, 100x + 2 > = < 2, 4 >

By comparing, e get

100y + 1 = 2 ........(1)

100x + 2 = 4 .........(2)

Divide equation (2) to equation (1) , we get

$\frac{100y + 1}{100x + 2} = \frac{1}{2}$

⇒2(100y+1) = 1(100x+2)

⇒200y + 2 = 100x + 2

⇒200y = 100x

⇒2y = x

Now,

As 2x + 4y = 1000

⇒2x + 2(2y) = 1000

⇒2x + 2x = 1000

⇒4x = 1000

⇒x = 250

Now,

As 2y = x

⇒2y = 250

⇒y = $\frac{250}{2}$ = 125

∴ we get

x = 250

y = 125

Now,

u(250, 125) = 100(250)(125) + 250 + 2(125)

= 3125000 + 250 + 250

= 3125000 + 500

= 3125500

⇒u(250, 125) = 3125500
