2 2 4

The given sequence is 2 2 4. To prepare for university exams, it is important to understand the pattern or rule behind the sequence. Without any additional information, it is difficult to determine the exact pattern or rule in this case. However, we can try to examine the given sequence and see if we can find any patterns:

1. The first number (2) is repeated.
2. The second number (2) is repeated.
3. The third number (4) is the sum of the first two numbers (2+2).

Based on this observation, it seems that the pattern could be that each number in the sequence is the sum of the previous two numbers. If this is the case, we can extend the sequence as follows:

2 2 4 6 10 16 26 ...

To prepare for university exams, it is important to practice identifying patterns and understanding rules. This helps in solving problems and making connections between different concepts.
