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 next number in the sequence would be 25.

The difference between successive numbers increases by 2 at each step. 1.5 → 5 : 3.5 5 → 10.5 : 5.5 10.5 → 18 : 7.5 The next difference is thus 9.5. And the next number in the sequence is: 18 + 9.5 = 27.5

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

183 + 1 = 44 + 2 = 66 + 3 = 99 + 4 = 13Etc. The next number in the sequence would be 18, then 25, and so on.Ans 2.The previous answer contains an error.The next number in the sequence would be 18 (13 + 5),after which comes 24 (18 + 6 ) not 25.

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 next number could be 26 The next number could be 12 - - - - - - - - - The next number that is in the sequence is 12.

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

25 is the next number that appears in that sequence.

The difference between the numbers is increasing by 2 every time. Therefore, 18 + 9.5 = 27.5 is the next number in the sequence.

The next number in the sequence would be 25.

The difference between successive numbers increases by 2 at each step. 1.5 → 5 : 3.5 5 → 10.5 : 5.5 10.5 → 18 : 7.5 The next difference is thus 9.5. And the next number in the sequence is: 18 + 9.5 = 27.5

This appears to be an arithmetic sequence with the difference increasing by 2 at each step. 1.5 → 5 (3.5) 5 → 10.5 (5.5) 10.5 → 18 (7.5) The next number in the sequence is 18 + 9.5 = 27.5

The next number in the sequence is 480

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

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)
