You should first multiply 5 by ( R + 2 ) so you gonna have : 5 R + 10 and now you can add -6 so you gonna have : 5 R + 10 - 6 = 5 R + 4 so the answer is 5R + 4 :)))

5(r+2) - 6

Apply the distributive property.

5*r = 5r
5*2 = 10

5r + 10 - 6

Combine like terms

10-6 = 4

5r + 4

Final answer: 5r + 4

What are the steps for this problem? -10-8n=n-(8n+8)

Elden [556K]

Answer:

$n = - 2$

Step-by-step explanation:

$- 10 - 8n = n - (8n + 8)$

First, you should distribute the -1 on the right.

$- 10 - 8n = n - 8n - 8$

Next, add 8n to both sides. This should cancel out the 8n.

$- 10 = n - 8$

Now, add 8 to both sides. This will get n by itself.

$- 2 = n$

Your answer is n = -2.

Answer:

5th term of sequence = -18

nth term of the sequence = -5n + 7

Step-by-step explanation:

Difference between successive and previous term of the output,

$T_{2}-T_{1}$ = -3 - 2

= -5

Similarly, $T_{3}-T_{2}=-8-(-3)$

= -5

There is a common difference 'd' = (-5)

Therefore, the sequence formed will be an arithmetic sequence.

First term of the sequence 'a' = 2

Explicit formula of an arithmetic sequence, $T_{n}$ = a + (n - 1)d [n = input value]

$T_{n}$ = 2 + (n - 1)(-5)

= 2 - 5n + 5

= -5n + 7

5th term of this sequence,

$T_{5}=2+(5-1)(-5)$

= 2 - 20

= -18

Therefore, 5th term of sequence = -18

nth term of the sequence = -5n + 7
