what is d?
no no. I dont understand the question. But I don't know much about arithmetic sequences. Is that what you are doing?
is it arithmetic sequence though ? I assume it is because a lot of people use d to mean common difference but I'm pretty sure it is not universal notation.
Yes it's an arithmetic sequence.
if it is an arithmetic sequence, the sequence goes like this: \[a_1,a_1+d,a_1+2d,a_1+3d,...\]
a1 is the first term a1+d is the second term ... a1+(n-1)d is the nth term
ok so a1=-10 and you know a2=?
well a1+d isn't -20 Ok I'm going to use the x-axis as the n-axis and the y-axis as the outputs
so graphing (1,-10) and (2,-7)
Oh so it's A.
|dw:1436740876427:dw| I ran out of room so I pretending -10 is someone down there
that is just graphing two points we can continue to plot more and more
and yes graph A is it
