Number of cards = 504 ÷ 126 = 4.
Biggest number = smallest number + 6.
Since all numbers are odd, each number differs from the next biggest/smallest by 2.
2nd biggest = smallest + 4.
3rd number = smallest + 2.
Total value = 4 of smallest value + 2 + 4 + 6 = 4 x smallest + 12
Subtract 12 from 504 to find 4 x smallest number. 504 - 12 = 492. Smallest number = 492 ÷ 4 = 123
