find the sixth term of the sequence a(n)=6+(n-1)(-2)

Question

please explain

Answer 1

find the range y=-3x+7 for the domain {-8, -6, -3, -2, 2}

to find the range all i have to do is plug the domain as x and y should be the answer, right?

Answer 2

just replace n with 6
a(6) = 6 + (5)(-2)
= -4

2nd question: correct

let x = -8, y = -3(-8)+7 = 31
let x = -6, y = -3(-6)+7 = 25
...
let x = 2, y = -3(2)+7 = 1

so the range is {31, 25, ... ,1}

Answer 3
