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>

Three times a number plus three times a second number is fifteen. Four times the first plus twice the second number is fourteen.
Alexxx [7]

Answer:

x = 2 | y = 3. ( 2,3 )

Step-by-step explanation:

2(3x + 3y = 15)

6x + 6y = 30

3(4x + 2y = 14)

12x + 6y = 42

- 6x. -6y. -30

6x = 12

÷ 6. ÷6

x = 2

3x + 3y = 15

3(2) + 3y = 15

6 + 3y = 15

-6. -6

3y = 9

÷3. ÷3

y = 3
