13, 14, 16 - the numbers increase by 1 then 2 each time
Unless you specify the length of the sequence, it is infinite, and so no number completes it. Given no further information, I would say the next number is 18. However, check out the link to the OEIS which gives a number of alternatives.
The numbers are increasing by 1,4,9,16,25,36.... which are square numbers so the next increase is 49. Making the next number in the sequence 141
The sequence continues: 49, 64, 81, 100, 121, 144, 169, 196, 225, .... The given sequence is the squares of the numbers 2, 3, 4, 5, 6 so the next numbers in the sequence are the squares of 7, 8, 9, 10, 11, ...
The next number in this sequence is 13112221.
Fibonacci found a way to present mathematical numbers so that each number in the sequence is the sum of the two previous numbers. For example, if the sequence starts at 0 and 1, then next number in the sequence is 1, the next number would be 2, and then the next number would be 3, and then 5.
56 (just the next number, not the number that completes the 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 is 485.
A sequence never ends. The next number in this one is 7 .
A single number, such as 172516261546 does not represent a sequence.
Unless you specify the length of the sequence, it is infinite, and so no number completes it. Given no further information, I would say the next number is 18. However, check out the link to the OEIS which gives a number of alternatives.

One numbers, such as 9162433, cannot comprise a sequence.
The sequence continues: 49, 64, 81, 100, 121, 144, 169, 196, 225, .... The given sequence is the squares of the numbers 2, 3, 4, 5, 6 so the next numbers in the sequence are the squares of 7, 8, 9, 10, 11, ...
The next number in this sequence is 13112221.
The difference between consecutive numbers is 1, 2, 3, 4. So the next difference will be... Added to 13 gives...
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
