Answer is Right!
Answer is Wrong!
The answer is $\boxed{31}$.
The sequence is a list of numbers that are generated by the following rule:
- Start with the numbers $0$ and $2$.
- Add $1$ to the first number, and $3$ to the second number.
- Repeat the process, adding $1$ to the first number and $3$ to the second number.
The first few numbers in the sequence are:
$0, 2, 3, 5, 8, 10, 15, 17, 24, 26, 31$
The missing number is $31$.
