New math riddle 🥳 The sequence {1, 10, 100, 1000, …} has the property that you can never get the same sum twice only using elements of this sequence. E.g. 110 = 10 + 100. No other way to get this sum What’s the slowest-growing sequence of increasing positive integers with this “a + b ≠ c + d” property?
