Find the common difference of the arithmetic sequence 13, 21, 29, ...

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

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.

+1 +3 +5 +6

i would guess 26 because this isnt a sequential pattern or its to short to know
