For a geometric series with first term a and common ratio the sum of infinite terms can be determined if `r < 1` and is equal to `a/(1 - r)`

Here, the first term of the series is 2/5 and the common ratio is 6/5

As `6/5 > 1` it is not possible to find the sum of infinite terms.

**For the given series the sum of infinite terms cannot be found.**
