What is the closed linear form for this sequence given a1 = -15 and an + 1 = an - 8?

Elza [17]

Answer:

<h3> $a_n=-8n-7$ is the closed linear form of the given sequence.</h3>

Step-by-step explanation:

Given that $a_1=-15$ and $a_{n+1}=a_n-8$

<h3>To find the closed linear form for this given sequence :</h3>

So each of the successive term of the given sequence is decreases by 8

Therefore the common difference is -8

The given sequence is a arithmetic sequence.

The general form is $a_n=a_1+(n-1)d$

Substitute $a_1=-15$ and d=-8 in $a_n=a_1+(n-1)d$ we get

$a_n=-15+(n-1)(-8)$

$=-15-8n+8$

$a_n=-8n-7$

<h3>Therefore $a_n=-8n-7$ is the closed linear form of the given sequence.</h3>

Solve the differential equation dy/dx = (x-2) / (y-2)

Brums [2.3K]

Answer:

y = 2 ± $\sqrt{x^2 - 4x + 4 + C}$

Step-by-step explanation:

Solve using separable equations

First put x and dx on the same side and do the same for y

(y-2)dy = (x-2)dx

Now you can integrate

$\frac{x^2}{2} +2x + C1 = \frac{y^2}{2} +2y\\$ + C1

Now we depending on how what ur instructor wants you may need to give exact solutions. We can do this by solving he quadratic equation for Y

Doing this you get:

y = 2 ± $\sqrt{x^2 - 4x + 4 + C}$

<em>Note C's were simplified.</em>
