Answer 3

Material 1: 15, 30, 60 is a difference of +15 then +30
Material 2: 13, 26, 39 is a difference of +13, +13
Material 3: 31, 62, 93 is a difference of +31, +31
Material 4: 14, 28, 42 is a difference of +14, +14

For material 1:
6 / 15 = 12 / 30 = 18 / 60
0.4 = 0.4 = 0.3
0.4 does not equal 0.3. Therefore, Material 1 will not work.

Answer 4

So that means that Material 1 is your answer
