$x,\left(x+1\right),\left(x+2\right),\left(x+3\right)_{ }$

$x+\left(x+1\right)+\left(x+2\right)+\left(x+3\right)$

$x-\left(x+1\right)-\left(x+2\right)-\left(x+3\right)$

$x\times\left(x+1\right)\times\left(x+2\right)\times\left(x+3\right)$

$A=\frac{1}{2}M+5$

$M=\frac{1}{2}A+5$

$A+5=2M$

$A+5=\frac{1}{2}M$
