What is then next number in the sequence?
2, 3, 5, 7, 11, 13, 17, 19, 23, _
To find the next number in the sequence, let's analyze the pattern.
This sequence appears to be a list of prime numbers in ascending order:
2, 3, 5, 7, 11, 13, 17, 19, 23, _
Therefore, the next prime number after 23 is 29.
So, the next number in the sequence is 29.
