Write the recursive rule and the iterative rule for the following sequence: 10, 6, 2, -2, -6

barxatty [35]

The recursive rule is
$a_n=a_{n-1}+(-4)$ .
The iterative rule is
$a_n=14-4n$

The recursive rule is given by the formula
$a_n=a_{n-1}+d$ , where d is the common difference. Our common difference is -4, which gives us the recursive rule above.

The iterative rule begins with the formula
$a_n=a_1+d(n-1)$ , where a₁ is the first term and d is the common difference. Our first term is 10 and our common difference is -4:
$a_n=10+(-4)(n-1)
\\\text{Using the Distributive Property,}
\\
\\a_n=10+(-4*n)+(-4*-1)
\\
\\a_n=10-4n+4
\\
\\\text{Combining like terms,}
\\
\\a_n=14-4n$

Can somebody help me with this question plz !

Answer:

y=4x-3

Step-by-step explanation:

Parallel lines will always have the same slope (the number that comes before x in an equation). So, we can plug in 4 to the equation.

y=4x+?

Let's say the ? is b. If we plug in the point (1,1) into y=4x+b, we get

1=4(1)+b

reduce

1=4+b

subtract 4 from both sides

-3=b

and now we can add b=-3 into the original answer, and we get y=4x-3!
