Solution(By ExamCraze Team)

Let the numbers be x, x + 2, x + 4, x + 6 and x + 8
Then,
$$ Rightarrow frac{{x + left( {x + 2} right) + left( {x + 4} right) + left( {x + 6} right) + left( {x + 8} right)}}{5} $$         $$= 95$$
$$eqalign{ & Rightarrow 5x + 20 = 475 cr & Rightarrow 5x = 455 cr & Rightarrow x = 91 cr} $$
So, the numbers are 91, 93, 95, 97 and 99
Clearly, the fourth number in the descending order is 93
