1. **State the problem:** Given that $a - b = b - c = 2$, find the value of the expression $$\frac{(a - b)^2 + (b - c)^2}{(a - c)^2}$$ 2. **Recall the given values:** We know that $$a - b = 2$$ $$b - c = 2$$ 3. **Find $a - c$:** Since $a - c = (a - b) + (b - c)$, substitute the known values: $$a - c = 2 + 2 = 4$$ 4. **Substitute into the expression:** $$\frac{(a - b)^2 + (b - c)^2}{(a - c)^2} = \frac{2^2 + 2^2}{4^2}$$ 5. **Calculate numerator and denominator:** $$= \frac{4 + 4}{16} = \frac{8}{16}$$ 6. **Simplify the fraction:** $$= \frac{\cancel{8}}{\cancel{16}} = \frac{1}{2}$$ 7. **Final answer:** $$\boxed{\frac{1}{2}}$$ This corresponds to option B) 1/2.
