Answer:
Diverges; no sum
Step-by-step explanation:
This is comparable to:
where:
r is the common ratio and
is the first term.
The series converges to:
![\text{First term}\cdot \frac{1}{1-\text{common ratio}}](https://tex.z-dn.net/?f=%5Ctext%7BFirst%20term%7D%5Ccdot%20%5Cfrac%7B1%7D%7B1-%5Ctext%7Bcommon%20ratio%7D%7D)
if the ratio's absolute value is less than 1.
This is a geometric series.
The common ration is -1.04 .
The first term in the series is 0.001.
Since the absolute value of -1.04 is 1.04>1, the series diverges.
