Question

The total number of fungal spores can be found using an infinite geometric series where a1 = 10 and the common ratio is 3. Find the sum of this infinite series that will be the upper limit of the fungal spores.

Answer 1

The answer is that the series is divergent! I hope this helps!!

Answer 2

If there is a common ratio of three there is no sum as the series diverges, there is no limit, it approaches +oo.  Maybe that is what they are looking for, +oo, but technically it is incorrect.  A limit is a numerical value, and oo is not a number.
