Answer:
I think the answer will be 20. It is oppsite sides and the lines look even. The area is small as well. So I think 20˙ will be the best option.
Assuming you already have your slope. Let’s assume you have a slope of 3/4. (m=3/4)
Slope intercept form is y=mx+b
y and x being a point
m is your slope
and b is your y-intercept
So for example, you have a y-intercept of 3, your equation would be y=3/4x+3
Standard form is Ax+By=C
It is adding 4 every time.
7 is the first term.
To get the 31st term, add 30*4 to 7 (why?)
The 31st term is 7+30*4=127
i belive it is -7 this may be your answer
