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)

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.

It seems that ecah number is obtained by squaring the previous number, then adding 2.

The formula would be the previous number plus the next number minus 1.

I'm fairly sure you meant the "4" to be a "3" in this sequence. There is no "next number" in the sequence given, since there is no rule that encompasses the entire sequence. And to be fair, in number sequences, any number can still logically be "next". If it's not the number that you expect, it is still a number sequence. It is just not a predicable one.

The next number is 4. 1, 3, 2, 5, 7, 4, 9, 11, 6

The sequence is generated using cubes, or n^3. The next number in the sequence will be 4^3, or 256.

The next number is 47. Each term is 1 more than double the term before it.

25 is the next number that appears in that sequence.

The next number is 4, followed by -2

16 is the next squared number.

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 next number in the sequence is 18. It's +1, +2, +3, +4, ....
