Will give brainliest to correct answer an arithmetic sequence is represented in the following table. enter the missing term of the sequence.

20 - (8 x 39) =

20 - 312 =

- 301

an altitude of 15,000 feet

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.
