Instructions: Write the explicit rule. Remember to simplify and do not put spaces in your answer. Sequence: 30,0,−30,−60,… 30 ,

Answer:

a(n)=60-30n

Step-by-step explanation:

Equation to use:

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

where a(1) is the first term, d is the common difference between terms, and n is the nth term you are trying to find.

In this case, a(1) is 30, d is -30, and n is just n.

If you plug that into the equation and use the distributive property, you would get: a(n) = 30 -30n + 30.

Adding the two 30's gets you: a(n) = 60 - 30n, which is the solution.

___________________________________________________
" Twenty-eight (28) students said they would vote for Brianna."

We are given, in the problem, that there are "45 students total" .
___________________________________________________
The fraction: $\frac{56}{90} ;$

can be reduced as follows:

$\frac{56}{90} = (56÷2) / (90÷2) = [tex] \frac{28}{45}$ .
___________________________________________________
Thus, "28 students out of 45 students voted for Brianna" .
___________________________________________________
The answer is: "28 students" .
