Answer:
Step-by-step explanation:
to find slope: the formula is:
(y2-y1) / (x2-x1)
in this case it is:
(-9-(-2)) / (-10-(-2))
-7/-8
and thats the slope (that was for question one, and also an example, now do the same for questions 2, 3 and 4!!
hope thsi helps!!
The common difference is x
the first term is x+1
a_8 = x+1 + x(8-1) = x+1 + 7x = 8x + 1
