What is the largest three-digit integer whose digits are distinct and form a geometric sequence with common ratio 2?

There are really only two numbers that satisfy this: 124 and 248. (The next possible one would be 36{12} which doesn't work in a base ten system.)

248 is the larger one and is therefore your answer.
