Which formula can be used to find any term ,n ,of the sequence 1,—2/3,4/

so, as we can see, it's really multiplying the previous term by -2/3, to get the next term, namely, -2/3 is the common ratio, and of course, the first term is 1.

sorry, can't i suggest going to algebra.com

step-by-step explanation:

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.
