A number is considered “odd-mult” is it is the multiple of exactly two consecutive odd numbers. How many positive numbers less than 400 are “odd-mult”?

Note: this is a grid-in question

What does this mean: “is the multiple of exactly two consecutive odd numbers.” I incorrectly thought that this meant that the number cannot be the multiple of any other number except these two consecutive odd integers. For example, 15 is the multiple of 5 and 7, and the multiple of no other number.
