It seems like you're asking for additional numbers to fill in the series. However, it's unclear how you would like to extend the sequence.
If you are looking for a pattern in the numbers you've provided (0.16, 0.35, 0.54), they increase by a consistent amount:
- The difference between 0.16 and 0.35 is 0.19.
- The difference between 0.35 and 0.54 is also 0.19.
Based on this pattern, the next two terms can be calculated as follows:
- The next term after 0.54 would be:
0.54 + 0.19 = 0.73 - The term following that would be:
0.73 + 0.19 = 0.92
So, the two terms to fill in would be 0.73 and 0.92.
If you meant something different, please provide more context or clarify your request!
