Answer:

Question 1:

(3)

x 3 5 7 9

f(x) 2 4 2 4

Question 2:

(2) whole numbers

Step-by-step explanation:

In a function, each x-value must only have 1 y-value, but a y-value can have multiple x-values.

A whole number is any positive number that is not a fraction. You cannot have negative devices nor a fraction of a device.

Let an denote the nth term of a geometric sequence. let a0=256 and an+1=0.5an .

dusya [7]

The explicit formula is $a_{n-1} = 256 * 0.5^{n-1$ and the sum of the first 25 terms is approximately 512

<h3>The explicit formula</h3>

The given parameters are:

$a_0 = 256$

$a_{n +1} = 0.5a_n$

Set n = 0

$a_1 = 0.5a_0$

Substitute 256 for a0

$a_1 = 0.5 * 256$

$a_1 = 128$

This means that the common ratio is 0.5.

The explicit formula is then represented as:

$a_{n-1} = a_0 * r^{n-1$

This gives

$a_{n-1} = 256 * 0.5^{n-1$

<h3>The sum of the first 25 terms</h3>

This is calculated using:

$S_n = \frac{a_0(r^{n-1} -1)}{r - 1}$

This gives

$S_{25} = \frac{256 * (0.5^{25-1} -1)}{0.5 - 1}$

Evaluate

$S_{25} = 512$

Hence, the sum of the first 25 terms is approximately 512
