These binomial equations are all true.
$\binom{7}{4} = \binom{4}{4} + 3[ \binom{4}{3} + \binom{4}{2}] + \binom{4}{1}$
$\binom{8}{4} = \binom{5}{4} + 3[ \binom{5}{3} + \binom{5}{2}] + \binom{5}{1}$
$\binom{9}{4} = \binom{6}{4} + 3[ \binom{6}{3} + \binom{6}{2}] + \binom{6}{1}$
$\dots$
Is this the result of some general binomial identity or theory?
My work
I stumbled upon this while working with a recurrence relation in $(m,n)$ with $m,n \in \Bbb Z^+$
that I was trying to put into closed form.
