Choose the equation that could be used to find three consecutive integers whose sum is 36 a) n + (n + 2) + (n + 4) = 36 b) n + (n + 1) + (n + 3) = 36 c) n + (n + 1) + (n + 2) = 36 d) n + (n - 1) + (n - 3) = 36

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
