Answer 2

Explicație pas cu pas:

$\large \bf \dfrac{P_{n + 1}}{P_{n}} = 42$

$\large \bf \dfrac{(n + 1)!}{n!} = 42$

$\large \bf \dfrac{(n + 1) \cdot n!}{n!} = 42$

$\large \bf \dfrac{(n + 1) \cdot \not n!}{ \not n!} = 42$

$\large \bf n + 1 = 42$

$\large \bf n = 42 - 1$

$\color{red}\Large \boxed{ \bf n = 41}$
