Answer:

a(n)=1+(n-1)(-3)

Step-by-step explanation:

Notice there's a common difference of d=-3.

If we use the formula a(n)=a1+(n-1)d to find the nth term given the first term and the common difference, we will see that the function that describes the arithmetic sequence as a(n)=1+(n-1)(-3)

D=a+b+c solve for b<br> I need some help

Hoochie [10]

Hi Walker

d=a+b+c

Flip

a+b+c=d

Add -a to both sides

a+b+c-a=d-a

b+c=-a+d

Now add -c to both sides

b+c-c=-a+d-c

b= -a-c+d

I hope that's help:0

Answer:

$a_7=-15$

Step-by-step explanation:

$a_n$ is given as the nth term of a sequence.

We want to find $a_7$ , which means we find the 7th term of the sequence.

Here, we simply substitute "7" into "n" of the formula given for $a_n$ to find the value of the 7th term of the sequence.

We show this below:

$a_n=-3(n-2)\\a_7=-3(7-2)\\a_7=-3(5)\\a_7=-15$

So the 7th term is "-15"
