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)

Think it's 30...then 20

The next number in this sequence is 13112221.

It looks like it is +6, -5, +12, -5. So I would assume the next number is +18, or 29.

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 in this sequence is 13112221.

the numbers next in series are 35,43,51,... any two consecutive terms has a difference of 8
