If you use each number 1-9 only once to form a 5-number sequence:
For the first number in the sequence you will have 9 options, for the second you will have 8 (excluding the number used in position one), for the third you will have 7 (9 minus the 2 already used) and so on.
9 X 8 X 7 X 6 X 5 = 15,120 unique combinations.
