( -2 , 0 , 1 )

#### Explanation:

Using the

#color(blue)" mid-point formula " # given 2 points

#(x_1,y_1,z_1)" and " (x_2,y_2,z_2) # then the midpoint of these 2 points is :

# [ 1/2(x_1+x_2) , 1/2(y_1+y_2) , 1/2(z_1+z_2) ] # For the points A(2,-3,1) and Z(-6,3,1) the mid-point is :

# [1/2(2-6) , 1/2(-3+3) , 1/2(1+1) ] = (-2 , 0 , 1) #
