Is there more context to the question?
Answer:
0.67
Step-by-step explanation:
Formula: k = y/x
k = 2/3
k = 0.66666666666
k = 4/6
k= 0.66666666666
k = 6/9
k = 0.66666666666
k = 8/12
Round 0.67
Hence, answer = 0.67

B, the first differences are not the same , that proves it is not linear. The second set of differences are the same this shows it is a quadratic function.
Y=1/2x+c
0=1/2 (10)+c
0=5+c
c=-5
the equation is y=1/2x+5
the slope is the same since these two lines are parallel
The sequence seems to be that you add 1 and then multiply by 2, and then add 1 and multiply by 3, so I would assume you do 9 + 1 = 10, and then multiply by 4 to get 40 as your next number. I hope this helps!
