That's the Fibonacci sequence! XD They're 21 and 34 if you add up the last two numbers to get the next one.

That's a Fibonacci sequence. After the first two numbers, each new number is the sum of the previous two numbers. The next number in that sequence would be 13.

The Fibonacci sequence. The Fibonacci Sequence is the series of numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... The next number is found by adding up the two numbers before it

34. Each number is the sum of the two preceding numbers. This is called the Fibonacci Sequence.

730,001, -260,776 and 532,901,720,777.

21. This is the Fibonacci series.

1, 4,9, 16, 25, 36,49 this is the next three sequence po

The next three numbers are: 87, 141, 228. Each number in the sequence after the first two is the sum of the previous two numbers. This is a variation of the Fibonacci sequence which starts with 1, 1, ... (and then continues ..., 2, 3, 5, 8, 13, ...).

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.

These are Fibannoci's numbers. Therefore, the 7th number is 21.

The next number in the sequence is 6. The numbers represent the scores travelling around a regular dartboard, clockwise from the top.

13, 14, 16 - the numbers increase by 1 then 2 each time

This is called the Fibonacci sequence. The last two numbers in the sequence are added together to produce the next. Therefore, following 8 and 13 are: 8 + 13 = 21 13 + 21 = 34 21 + 34 = 55 34 + 55 = 89 55 + 89 = 144

Since this appears to be the start of the Fibonacci sequence, the next number would be 21, which is found by adding the two previous numbers (8 + 13 = 21).

The Fibonacci Series 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ...

Start with the numbers 1 and 1. After that, every number in the sequence is the sum of the previous two numbers. Thus, the sequence starts with: 1, 1, 2, 3, 5, 8, 13, ...

3,5,8,13 is followed by 21. 1,1,2,3,5,8,13,21,34,55,... is the Fibonacci series or Fibonacci sequence where the next number in the sequence is the sum of the last two numbers (1+1=2, 1+2=3, 2+3=5, etc.)

If you mean, what is the pattern, it is the first three prime numbers. The next one would be 7, then 11, then 13 and so on. Also, there is a sequence of numbers called the Fibonacci sequence, which goes 1, 1, 2, 3, 5, 8, 13, 21, ... (you add the two previous numbers to get the next one). Although your numbers 2, 3, 5 are in this list, I don't think that is what is meant by your example, since the 1, 1 are missing in the beginning. So, I would say, "it is the first three prime numbers".
