Find the 20th term of the following sequence.
-6, -4,-2, O,...

Step-by-step explanation:

An=-6+(20-1)×2

=-6+19(2)

=-6+38

=32

32

Step-by-step explanation:

The sequence is x + 2

I.e = -6 + 2 = -4

-4 + 2 = -2

-2 + 2 = 0

The 20th term is 32

-6,-4,-2,0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30 ,32 ,34,36

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.
