Question

check the convergency for Σn/n+1​

Answer 1

Answer:

We can write this expression differently in order to find the limit:

(

n

n

+

1

)

n

=

(

1

n

+

1

n

)

n

=

1

(

1

+

1

n

)

n

So:

lim

n

→

∞

∣

∣

∣

a

n

+

1

a

n

∣

∣

∣

=

1

(

1

+

1

n

)

n

=

1

e

<

1

which proves the series to be convergent
