Let's rewrite the equation as
This should be enough to convince you that the equation has no solutions, no matter which value for k you choose. In fact, the left hand side of the equation is an absolute value, which by definition is always positive, or zero in the worst case.
The equality asks for this quantity to equal -3, a negative number.
A non-negative quantity can never equal a stricktly negative quantity, so the equation has no solutions.

Where will the mean approach if sample size increase
Using central limit theorem, we have:
This means that; as n approaches infinity, the mean is almost expected to the i.e. expected to remain unchanged.
Hence, the mean value will approach 51.
