As they are written, they are all linear. I think you meant for the third one to be y=x^2. if that is true then y=x^2 is a quadratic and therefore is the answer
Answer:
Equation of a line passes (x1, y1) in point-slope form:
y - y1 = a(x - x1)
Slope = -2 => a = -2
=> y - y1 = -2(x - x1)
That line passes (-2, 1)
=> x1 = -2, y1 = 1
=> y - 1 = -2(x - (-2))
<=> y - 1 = -2(x + 2)
Hope this helps!

Hello,
4. you have sequences defined by the first term and a recursive relation.
Take n = 2, it gives
, right?
But you know
so
This is the second term. You are asked to find the first three terms.
Now, let's take n = 3
So the first three terms are 3, 6, 12.
6.
8.
10.
Do not hesitate if you have any question.
Thank you
