  • Answer: [tex]4753[/tex]

    Step-by-step explanation:

    Given: The mystery number is a four-digit number.

    The digits used to make the number : 5, 4, 7, and 3.

    Since , 5 and the 7 are the two middle digits.

    Then , the number would look like [tex]-57-\ or\ -75-[/tex]

    The 5 comes after the 7.

    Then , the number would look like [tex]-75-[/tex]  [i.e.  [tex]-57-[/tex] is not representing  the mystery number]

    The 3 is not the first digit, then 4 must be the first digit.

    Hence, the mystery number should be : [tex]4753[/tex]
