#### To determine

**To explain:** The meaning of
∑n=1∞an=5
.

#### Answer

The sum of the series is 5.

#### Explanation

The sequence of partial sums
{an}
is closer to 5 as *n* approaches to larger number.

That is, the sequence of partial sums converges to 5 as *n* tends to
∞
.

Therefore, the sum of the series is 5.
