Given a term and the common difference of an arithmetic sequence find
the arithmetic rule. a37=-321 and d=-9.
(Your answer should be written like an=-5n+2).

An = -5n -140

Step-by-step explanation:     a37=-321 and d=-9

hello :

the n-ieme term is : An = Ap +(n-p)d

p=37     An = A37 +(n-37)(-5) = -321 -5n+185

An = -5n -140

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
