Three problem

Algebra Level 3

I want three integers a, b & c, such that

-the second it's 2 times the first

-the third it's 2 times the second

-and not to big (a, b and c are strictly less than 20)

You may think that you have not enough information, but if i tell you the number that i hate (that i don't won't in the integers) you must know exactly the triple i'm thinking.

a = 4, b = 8, c = 16 a = 2, b = 4, c = 8 a = 1, b = 2, c = 4 a = 3, b = 6, c = 12

These are all good solution for the first part of the problem, but there is only one number (the 4) that appear in 3 list, so it must be the number I hate and so the triple i'm thinking is 3,6,12
