Answer

To solve the problem, we need to identify the missing term in the sequence of prime numbers given as 2, 3, 5, 7, followed by the numbers 11, ..., 17, 19.

### Step-by-Step Solution:

1. **Identify the Sequence**: The sequence provided starts with the numbers 2, 3, 5, and 7. These are the first four prime numbers.

2. **List the Prime Numbers**: The next few prime numbers after 7 are:
- 11 (5th prime)
- 13 (6th prime)
- 17 (7th prime)
- 19 (8th prime)

3. **Locate the Missing Term**: In the sequence given (11, ..., 17, 19), we see that 11 is followed by a missing term and then 17 and 19. The prime number that comes after 11 is 13.

4. **Conclusion**: Therefore, the missing term in the sequence is 13.

### Final Answer:
The missing term is **13**.
