The sequences you've written appear to describe two separate series of fractions that decrease as the denominators increase.

Let's break down each sequence.

**First Series:**
1. \( \frac{1}{100} \)
2. \( \frac{1}{100.99} \)
3. \( \frac{1}{99.98} \)
4. \( \frac{1}{98.97} \)
5. Continuing in this manner downwards to \( \frac{1}{3.2} \)
6. and eventually to \( \frac{1}{2} \)

Notice that the denominators of the first series start from 100 and appear to decrease by roughly increments of 0.01 until reaching about 2.

**Second Series:**
1. \( \frac{1}{100} \)
2. \( \frac{1}{100.99} \)
3. \( \frac{1}{99.98} \)
4. \( \frac{1}{98.97} \)
5. Continuing down to \( \frac{1}{3.2} \)
6. and then to \( \frac{1}{2.1} \)

This series is similar to the first one but ends with \( \frac{1}{2.1} \).

If you were looking to sum these fractions or perform some other operation, please clarify, and I would be happy to help further.
