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.
The pattern in this sequence is multiplying by 2 and then adding the previous number squared. Starting with 1, we multiply by 2 to get 2, then add the square of the previous number (1^2) to get 3. Next, we multiply 3 by 2 to get 6, then add the square of the previous number (3^2) to get 11. Following this pattern, we multiply 11 by 2 to get 22, then add the square of the previous number (11^2) to get 133. Therefore, the next number in the sequence is 133.
42 is the next number in this sequence. This number sequence is adding the next prime number to the last number. So 1 + 2 = 3. Then 3 + 3 = 6, 6 + 5 = 11, 11 + 7 = 18, 18 + 11 = 29. The next prime number after 11 is 13, so 29 + 13 = 42. The next numbers would be 59 (42+17), 78 (59+19), and 101 (78+23)
23
These are all prime numbers. The next one is 17
This list of numbers is the list of prime numbers. Following 11, the next two numbers in the list are 13 and 17.
11
-3, -6, -11

42 is the next number in this sequence. This number sequence is adding the next prime number to the last number. So 1 + 2 = 3. Then 3 + 3 = 6, 6 + 5 = 11, 11 + 7 = 18, 18 + 11 = 29. The next prime number after 11 is 13, so 29 + 13 = 42. The next numbers would be 59 (42+17), 78 (59+19), and 101 (78+23)

Sequence is +4 - 3 + 5 - 2 + 6 - 1 (+1 - 1)2 6 3 8 6 12 next number 11
It all depends on the sequence you are talking about. For example, the next number in the sequence 0,1,1,2,3,5,8,13,_ would be 21. This would be the Fibonacci sequence as the rule is add the 2 previous terms to get the next term. Another example would be this: 11,121,1331,14641,______.The missing number is 161051, following the pattern of powers of 11, 11^1, 11^2, 11^3 and so on. If you understand what I am trying to say, it all depends on the sequence you are trying to find the number in.
17, it's the sequence of primes.
it has to be 11
This list of numbers is the list of prime numbers. Following 11, the next two numbers in the list are 13 and 17.
