Question

Prove it, need urgently ​

Answer 1

Equation: [(n+1)/2]² > n

To prove this, use an instance where n is any real number.

When n = 2,

-> [(2+1)/2]²
-> [3/2]²
-> 2.25

2.25 > 2 so equation is correct.

It will also work with negative n because if you square a negative number, it will yield a positive result.
