If repeating a number is not allowed :

27*26*25 = 17,550

Answer: There are 2925 different sequences without repeating a number.

Step-by-step explanation:

Since we have given that

Numbers = 1 to 27

We have to use only 3 numbers to padlock for your gym locker.

We will use "combination" for finding the number of different sequences.

So, it becomes,

[tex]^{27}C_3=2925[/tex]

Hence, there are 2925 different sequences without repeating a number.
