∀ n€N[(the) sum of an (infinite?) series (a1,+a2,...+,an)] (where [tex]a_{n}[/tex]=[tex]\frac{n}{(n+1)!}[/tex])

[tex]\sum \frac{n}{(n+1)!}[/tex](is equal to/gives/yields)=1 -[tex]\frac{1}{(n+1)!}[/tex]

Prove that:

∀ n [tex]\in[/tex] N[tex]\sum \frac{n}{(n+1)!}[/tex]=1 -[tex]\frac{1}{(n+1)!}[/tex]

THX in advance
