Answer:

The fourth number is 92

Step-by-step explanation:

Let the fourth number be represented with x

Mean = Total sum of values / No of given values

Mean = 88

[tex]88= \frac{80+95+85+x}{4}\\ \\88=\frac{260+x}{4}\\ \\Cross\:Multiply\\\\88\times 4 = 260+x\\352= 260+x\\352-260=x\\92=x\\\\x=92[/tex]
