I believe "BY || JE" means that those two lines are congruent, which means the slope of JE would be the same as the slope of BY. So in this case the answer should be B. -1/5.
I hope this helped.
Assume the smaller one is x, then the other ones will be x+2 and x+4
x(x+2) + 2 = 5(x+4)
x^2 + 2x - 5x - 18 = 0
-> x^2 - 3x - 18 = 0
-> (x-6)(x+3) = 0
-> x = 6 or -3, since x must be positive, then x = 6
So the numbers are: 6, 8, 10
