Question

if drawing this value scale, why would it be a good idea to fill in boxes 3 and 7 next?
1 2 3 4 5 6 7 8 9
because they add up to 10.
because they are mid - points.
because they are odd numbers.

Explanation:

In a value scale (used in art for shading/tonal range), the mid - points between the light (e.g., box 1 - 2), middle (box 5), and dark (box 9) areas help in creating a smooth gradient. Box 3 is the mid - point between box 1 (light) and box 5 (middle), and box 7 is the mid - point between box 5 (middle) and box 9 (dark). The option about adding to 10 is irrelevant to value scale logic, and being odd numbers doesn't relate to tonal progression. So the correct reason is they are mid - points.

Answer:

B. Because they are mid - points.
