Which is the function describe the arithmetic sequence shown ? 3,7,11,15,19,23
r-ruslan [8.4K]
<h3>a_n = 4n-1 is the function describe the arithmetic sequence</h3>

<em><u>Solution:</u></em>

<em><u>Given arithmetic sequence is:</u></em>

3, 7, 11, 15, 19, 23

<em><u>The nth term of arithmetic sequence is given as:</u></em>

a_n = a_1+(n-1)d

Where,

n is the nth term

d is the common difference between terms

a_1 is the first term of sequence

From given,

3, 7, 11, 15, 19, 23

Common difference, d = 7 - 3 = 4

a_1=3

<em><u>Substituting the values in formula,</u></em>

a_n = 3 + (n-1) \times 4\\\\a_n = 3 + 4n - 4\\\\a_n = 4n-1

Where, n is positive integer, n\geq 1

Thus the function that describes the arithmetic sequence is found

Choose the equation that represents the line passing through the point (2, - 5) with a slope of −3.A y = −3x − 13 ,B y = −3x + 1
timurjin [86]

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3, thus

y = - 3x + c ← is the partial equation

To find c substitute (2, - 5) into the partial equation

- 5 = - 6 + c ⇒ c = - 5 + 6 = 1

y = - 3x + 1 → D
