The positive odd integers.

The next number in this sequence is 13112221.

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)

There is the Morris number sequence and the Fibonacci number sequence. The Padovan sequence. The Juggler sequence. I just know the Fibonacci sequence: 0,1,1,2,3,5,8,13,21,34,55,89,144,233,377 Morris number sequence: 1 11 21 1211 111221 312211...

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.

The lucas numbers are a sequence of numbers. They go as 1, 3, 4, 7, 11, 18 etc the sequence is bery similar to the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13)
It seems that ecah number is obtained by squaring the previous number, then adding 2.
