Vemos en ellos que el segundo tiene los mismos factores que el
primero, con el añadido de su media aritmética que también es prima.
Los tres forman una progresión aritmética:
Si en una terna de primos en progresion aritmética multiplicamos
los dos extremos obtenemos un arolmar semiprimo y si
multiplicamos los tres, un arolmar de 3 factores. Coinciden las
dos generaciones paralelas.
