Suppose that 10 &lt; n &lt; 11. A possible value for n is
-BARSIC- [3]
★ Inequalities ★

10 < n < 11 \\
or n ∈ ( 10 , 11 )
Possible value can be easily obtained by generating an arithmetic mean

n = \frac{10 + 11}{2}  = 10.5
Else we've infinite numbers between them ,
According to density property of real numbers , we can have any real number satisfying the given inequality under condition 10 < n < 11
Which is true for infinite possible numbers
10.1 , 10.2 , ... INFINITY
