While there are not enough numbers to fully establish the sequence, the difference could be increasing by 3 each time, therefore, the sequence will go: 2, 5, 11, 20, 32...
Or, the differences could be doubling each time, meaning that the sequence will go: 2, 5, 11, 23, 47...
The next number in this sequence is 13112221.
The next two numbers in the sequence are 13 and 17. This sequence consists of prime numbers, which are integers greater than 1 that have no positive divisors other than 1 and themselves. After 11, the next prime number is 13, followed by 17.
5, 11, 17
This list of numbers is the list of prime numbers. Following 11, the next two numbers in the list are 13 and 17.
The next number in the sequence would be 23. The sequence consists of prime numbers.
The sequence 14567911 appears to be a series of increasing odd numbers: 1, 5, 7, 9, and then jumps to 11. Following this pattern, the next odd number after 11 is 13. Therefore, the next number in the sequence is 13.
11, -10, 9
17
11 and 8
They are a sequence of odd numbers. The next three in the sequence would be 17,19 & 21
These are all prime numbers. The next one is 17
Two possible answers spring immediately to mind. First, this sequence appears to be a list of the first five prime numbers; in this case, the next number in the sequence would be 13. Second, the intervals between these numbers comprise the sequence "1 2 2 4", in which the nth number equals the product of the (n-1)th and (n-2)th numbers. Based on this, the next number in the given sequence would be 11 + (4*2) = 19.
