The recursive formula
means that the next term in the sequence is 5 more than the previous one.
So, we know that we start from
, which means that the next term is

Similarly,

You will add the two numbers together and add the t as well to make 33t
I get the answer being the same y= -1/2x +
Because b in intercept form is "0"
I used
m=y2-y1/x2-x1
M=-3-2/6-4
M=-5/10
M=-1/2
(-4,2)
Y=mx+b
2=-1/2 (-4)+b
B=2-(-1/2)(-4)
B=0
I did the same for second point
And got "0" for b
So my answer is get
Y=-1/2x
Unless someone else gets something else different.
I hope somewhat helps
