Answer:
68 is the fourth number.
Step-by-step explanation:
The average of the 4 numbers is 45.
Hence, the total of the four numbers is [tex]45 \times4[/tex] = 180.
The given three numbers are 24, 36, 52.
The total of the given three numbers is (24 + 36 + 52) = 112.
The fourth number will be (180 - 112) = 68.
