The nest number in the sequence is 18. Note that the difference between each number and the next number in the sequence follows the simple sequence of 1,2,3,4. Obviously the next in the sequence of increases is 5, so 13+5=18.

If the last number is 1/3 (it should be), the next number is 5 and 1/3
The rule for this sequence appears to be adding consecutive prime numbers. The sequence starts with 3, then adds the next prime number 2 to get 4. It then adds 3 (the next prime number) to 4 to get 7, then 5 to 7 to get 12, and so on. Each number in the sequence is the sum of the previous number and the next prime number in order.
To find the next number in the sequence -5, -2, 4, 13, we can look at the differences between consecutive terms: -2 - (-5) = 3 4 - (-2) = 6 13 - 4 = 9 The differences are 3, 6, and 9, which increase by 3 each time. Following this pattern, the next difference should be 12. Therefore, adding 12 to the last term (13) gives us 25, making the next number in the sequence 25.

The next number in the sequence is 18. It's +1, +2, +3, +4, ....
Every next number is increased by 5. The next number in the sequence is 23.
The sequence is decreasing by a factor of 5 each time, so the next number would be -2.

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)
