what are the next 2 numbers in this sequence: 20 , 1 ,18 ,4 ,9 ,1
13, 21 - it is the Fibonacci sequence
This list of numbers is the list of prime numbers. Following 11, the next two numbers in the list are 13 and 17.
54
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.
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
7^2 = 49 and 8^2 = 81
In fact, what are the next 2 numbers: 7, 14, 17, 21, 27, 28, 35, 37, ?, ? The next two numbers are 42 and 47. It's a set of numbers that contain or can be divided by 7.
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.
It can be any number. Two numbers do not even determine whether the "sequence" is arithmetic, geometric or other.
