Explanation:

900

- Let's examine the series further to find the mistake.
- The series: 18.3, 20.6, 16, 22.9, 13.7, 2.2, 11.4
- Notice the pattern: alternate numbers slightly increase and then decrease.
- For instance, from 18.3 to 20.6, there's an increment.
- But from 20.6 to 16, there's a notable decrease.
- Going on, from 16 to 22.9, there's another increase.
- However, when we move from 22.9 to 13.7, the drop is unexpectedly steep.
- Continuing, from 13.7 to 2.2 seems too big a drop.
- **The correct answer appears to be: Option 2, 16.** ☑️
