Let E=x
F-E=E-D
F+D=2E
3^16-x=x-3^15
3^15(3+1)=2x
x= 2 * 3^15
Now 2 x 3^15 - 3^15 = 3^15 (distance between any 2 points on this line)
D - 3^15 = C
3^15 - 3^15 = 0
C is 0
A x C = 0 (D)
F-E=E-D
F+D=2E
3^16-x=x-3^15
3^15(3+1)=2x
x= 2 * 3^15
Now 2 x 3^15 - 3^15 = 3^15 (distance between any 2 points on this line)
D - 3^15 = C
3^15 - 3^15 = 0
C is 0
A x C = 0 (D)
