This sequence is constructed from the sum of successive pairs of primes. The next number is 30.
2+3 = 5
3+5 = 8
5+7 = 12
7+11 = 18
11+13 = 24
13+17 = 30
17+19 = 36
19+23 = 42

Just add each pair of consecutive prime numbers to find the next number.
It is very likely, however, that this solution is not unique.

What number is next in this sequence 3 4 6 9 13?
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.
What number comes next in this number sequence 90 72 56 42 30?
92 - 18 = 72 72 - 16 = 56 56 - 14 = 42 42 - 12 = 30 30 - 10 = 20 20 is the next number in the sequence.
What is the next term in the sequence 60.75 40.5 27 18?
12, 8
What is the rule for this sequence 3 4 6 9 13 18?
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.
What is the next number in the sequence 4-11-18-25?
It is obvious that 7 is added to get the next number from the previous one.
