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.

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.

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

The sequence indicates that one number is added to the previous number to find the value of the next number. Example 1 (+0) - 1 (+1) - 2 (+1) - 3 (+2) - 5 (+3) - 8 (+5) - 13. The next number in the sequence would be 21 (13 + 8).

18

If the last number is 1/3 (it should be), the next number is 5 and 1/3

The sequence is taking half of the number and adding it to that number, 3/2 = 1.5, 3 + 1.5 = 4.5, the next number in the sequence is 15.1875

21

The next number would be 18. The sequence increases with +1, +2, +3... +5 etc. 13 + 5 = 18

The sequence is generated using cubes, or n^3. The next number in the sequence will be 4^3, or 256.

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)

These are all prime numbers. The next one is 17

The next number is 36. The sequence is called the youarequeer sequence and is made by adding the former number to the latter ie. poop dookie doo doo and diarrea, and so on.

13, because if you add the last number to the current number you get the next number

The next is 3.

18 b/c the pattern is +1,+2,+3...

17, it's the sequence of primes.

Each following number in the sequence is being divided by 4. Therefore, the next number in the sequence is 3/4 = 0.75.
