what are the next 2 numbers in this sequence: 20 , 1 ,18 ,4 ,9 ,1
The sequence appears to involve multiplying the previous number by an increasing factor: (4 \times 5 = 20) and (20 \times 5 = 100). Following this pattern, the next number would be (100 \times 5 = 500), and then (500 \times 5 = 2500). Therefore, the next two numbers in the sequence are 500 and 2500.

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.

The next number is 47. After this series gets going, each number is the sum of the two numbers before it. If the first two numbers were zero and 1, this would be the Fibonacci series.
The next number in the sequence would be 23. The sequence consists of prime numbers.
