First you need to find the the mid point of AB. x-coordinate=(-7+8)/2=.5 y-coordinate=(-6-9)/2=-7.5. Find the slope between C and the mid point. m=19.5/1.5=13. Plug into slope intercept form. Y-12=13(x-2).
ANSWER!!!! y=13x-14
first term = initial number
second term = initial number + common difference
third term = initial number + 2(common difference)
So...
2x+5-(x+4) = common difference
4x+3-(2x+5) = also common difference
2x+5-(x+4) = x+1
4x+3-(2x+5) = 2x-2
Because x+1=2x-2 we can solve for x.
x=3
So the sequence goes... 7,11,15...
19 is the fourth term
