Answer: \(4753\)
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 \(-57-\ or\ -75-\)
The 5 comes after the 7.
Then , the number would look like \(-75-\) [i.e. \(-57-\) 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 : \(4753\)
