The next number in the sequence would be 23. The sequence consists of prime numbers.

11.

Actually the next number in the sequence is 17 A 19 , 23 , 29 , 31 ,.......... Prim number

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)

2 is the answer

15

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.

17?

These are all prime numbers. The next one is 17

23

The next number in the sequence 5-7-13-31 is 69.

13

17, it's the sequence of primes.

1595. To find each digit in the sequence you have to reverse the numbers (for example , 13 reversed is 31), then add that number to the original (for example the original is 13), so the next number in the sequence is 31 + 13 = 44, and so on. It is palindromic.

The next number in the sequence is 27.

The next number in the sequence is 27.

Each ascending number is equal to the square of the next prime number multiplied by (the prime number plus one). In this case, 11 squared x 12 = 1452. Therefore, the next number in the sequence is equal to 13 squared x (13 + 1) = 13 squared x 14 = 2366.Following this, the next number would be 17 squared x 18 = 5202.

There are many possible answers. One obvious one is 13, the next number in the Fibonacci Sequence that yields the golden mean.

The sequence is decreasing by a factor of 5 each time, so the next number would be -2.

Every next number is increased by 5. The next number in the sequence is 23.

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.

yes it is
