Answer:
The sequence is arithmetic because the terms have a common difference
Step-by-step explanation:
The difference between each term in the sequence is constant. The sequence shown below, considering the y values of the coordinates, are 9, 7.5, 6, 4.5, 3, 1.5. Each term has a difference of 1.5, thus making all terms have a common difference, and making the sequence arithmetic.
Gradient means slope'
y=mx+b
m=slope
y=6x+5
6=slope
answer is 6
