For this installment of Word Problem Wednesday, we're on the hunt for a mystery number! Using the clues below, can you figure it out? We'll update this article with the answer tomorrow!

I am a three-digit odd number. My ones digit is divisible by 3. My hundreds digit is twice as large as the ones digit. The tens digit is five less than the hundreds digit. What number am I?

Update: Here's the solution!

The ones digit is divisible by 3, so the ones digit can be 3, 6, or 9. The hundreds digit is twice as large as the ones digit. 3 doubled is 6, 6 doubled is 12, and 9 doubled is 18. Since 6 is the only option that is one digit, the hundreds digit must be 6 and the ones digit must be 3. The tens digit is five less than the hundreds digit. The hundreds digit is 6, so the tens place is 1. The number is 613!
