13, 14, 16 - the numbers increase by 1 then 2 each time
The sequence appears to alternate between adding and subtracting numbers. The pattern seems to be +11, -7, +5, -2, +6. Following this pattern, the next number in the sequence would be +3 from the previous number, which would be 21.
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
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 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.
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 .
The sequence appears to alternate between adding and subtracting numbers. The pattern seems to be +11, -7, +5, -2, +6. Following this pattern, the next number in the sequence would be +3 from the previous number, which would be 21.
A single number, such as 172516261546 does not represent a sequence.
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
One numbers, such as 9162433, cannot comprise 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.
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...
