"Web1st central moment = $0$. 2nd central moment = $\lambda$. Using these in the equation you will find the 3rd central moment is $\lambda.$ (Bear in mind that all central moments are zero when $\lambda=0,$ implying the differential equation has a unique solution.) Again use the 2nd and 3rd central moments to obtain the 4th and so on. " - Fourth central moment

Because the raw kurtosis of the normal distribution is 3, it is common to define the excess kurtosis as μ ~ n − 3. A distribution that has a negative excess kurtosis has thinner tails than the normal distribution. An example is the uniform distribution.
