Now I know how this works- but I came across this example and even though I know the answer- the simplification given in the explaination doesn't make sense to me.(adsbygoogle = window.adsbygoogle || []).push({});

the squence is a_{n}= {5^{n}/n!}

now applying a_{n+1}and dividing a_{n+1}/a_{n}

the book indicates = 5/n+1

this is what I don't get how

(5^{n+1}/(n+1)!)/(5^{n}/n!) can simplify to that ?

can someone explain please- what am I missing here.
