Each new number in the series is the sum of the previous two numbers. That sequence is part of an infinite series called the Fibonacci series.
0, 1, 1 (0+1), 2 (1+1), 3 (2+1), 5 (2+3), 8 (3+5), 13(5+8), 21 (13+8), 34 (21+13),....and so on.
21 and 13. The pattern is t(n) = (-n4 + 10n3 - 23n2 + 38n - 12)/12
You add the 2 numbers before e.g. 2+3=5
1, 1, 2, 3, 5, 8, 13, 21... is the Fibonacci SeriesIt could as well be a series of prime numbers :1, 2, 3, 5, 7, 11, 13, 17, 19, etc.
There are 2 missing. The sequence is 1,1,2,3,5,8,13,21. the equation is na=na-1+na-2. 1+1=2,+1=3,+2=5,+3=8,5=13,+8=21 The numbers you are missing are 1 and 8
0, 1, 1 (0+1), 2 (1+1), 3 (2+1), 5 (2+3), 8 (3+5), 13(5+8), 21 (13+8), 34 (21+13),....and so on.
21 and 13. The pattern is t(n) = (-n4 + 10n3 - 23n2 + 38n - 12)/12
A Fibonacci pattern always begins with two numbers you choose (usually begins with 0 and 1, but can begin with any two numbers you choose). The third number in the sequence is found by adding the previous two numbers. This pattern continues until you choose to stop.EXAMPLE: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, etc.EXPLAINED: 0, 1, (0+1=1), (1+1=2), (1+2=3), (2+3=5), (3+5=8), (5+8=13), (8+13=21), (13+21=34), etc.
5-8-13-21-34-56-90.... The next number is the sum of the two previous numbers. This is the Fibonacci sequence, 1-1-2-3-5-8-13-21-34-56-90 etc
55 and 89
You add the 2 numbers before e.g. 2+3=5
It could be 31 ad 43
The prime numbers from 1 to 21 are 2, 3, 5, 7, 11, 13, 17, and 19.
The sequence 1-1-2-3-5-8-13 is known as the Fibonacci sequence. In this sequence, each number is the sum of the two preceding ones, starting from 1 and 1. Thus, the next numbers would be 21 (13 + 8) and 34 (21 + 13). This pattern continues indefinitely.
1, 1, 2, 3, 5, 8, 13, 21... is the Fibonacci SeriesIt could as well be a series of prime numbers :1, 2, 3, 5, 7, 11, 13, 17, 19, etc.
This is the Fibonacci sequence where each new number is the sum of the last two numbers. So the next numbers are: 8 + 13 = 21 13 + 21 = 34 21 + 34 = 55 34 + 55 = 89 55 + 89 = 144
If you mean: 1 1 2 3 5 8 13 21 then the next number is 13+21 = 34
