Answer:
The convergent series are;

(And)

Explanation:
A series in mathematics is the sum of a sequence of numbers to infinity
A convergent series is a series that sums to a limit
From the given options, we have;
First option

As 'n' increases, 2·n becomes more larger than n + 1, and the series diverges
Second option

As 'n' increases, n² - 1, becomes more larger than n - 2, and the series diverges
Third option

As 'n' increases,
, becomes more smaller and tend to '0', therefore, the series converges
Fourth option

As 'n' increases,
, becomes more smaller and tend to '0', therefore, the series converges
Fifth option

As 'n' increases,
, becomes more larger and tend to infinity, therefore, the series diverges.
