    Gamma Random Variable

    how do Γ(a+3) and Γ(a) compare?

    do i need to evaluate the integrals, or is there a property that i can use. I only know the
    two properties:

    1)Γ(a+1)=aΓ(a) which holds for all values of a>0
    2)Γ(n)=n-1! when n is an integer

    Well (I'll put G for the Gamma function), G(a+3)=(a+2)G(a+2)=(a+2)(a+1)G(a+1)=(a+2)(a+1)a G(a) ?

    It would help if you posted the whole question.
