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:
$a_n=10+(-4)(n-1)
\\\text{Using the Distributive Property,}
\\
\\a_n=10+(-4*n)+(-4*-1)
\\
\\a_n=10-4n+4
\\
\\\text{Combining like terms,}
\\
\\a_n=14-4n$

The ordered pair (0,0)(1,4)(2,16)(3,36)(4,64). write a rule that represents the function.

gayaneshka [121]

Let x represent first number in pair and y represent second number. We can see that x numbers are increasing by 1 on each next pair. y numbers are square of 0,2,4,6 and 8

Knowing all of that let "n" represent the position of the pair starting from 0!

than we can write that the rule is:
(n,(2n)^2)

42 is 64% of what number

steposvetlana [31]

Answer: x = 65.63
Explanation:
We have, 64% × x = 42 or, 64/100 × x = 42
Multiplying both sides by 100 and dividing both sides by 64, we have x = 42 × 100 64
x = 65.63
