One possibility: -3
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)
47 4+7 = 11 7+11 = 18 11+18=29 18+29=47
-47, -41, -35, -29, -23, -17, -11, -5, 1, etc.
127.
16 21 22 29
It looks like it is +6, -5, +12, -5. So I would assume the next number is +18, or 29.
47, you add the two previous numbers together: 3+4=7 4+7=11 7+11=18 18+29=47.
41
If you mean: 7 18 29 40 then the next term is 40+11 = 51
These are just the first prime numbers. The next few are 13, 17, 19, 23, 29, 31...
Actually the next number in the sequence is 17 A 19 , 23 , 29 , 31 ,.......... Prim number
29, assuming it is an algebraically reclusive sequence.
