what are the next 2 numbers in this sequence: 20 , 1 ,18 ,4 ,9 ,1
9
The next two numbers in the sequence are 13 and 17. This sequence consists of prime numbers, which are integers greater than 1 that have no positive divisors other than 1 and themselves. After 11, the next prime number is 13, followed by 17.
-20, -14, 28
The next four number in the sequence are... 4,5,5 & 6
21. Add the last 2 numbers to get the next.

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
43, 1806
This list of numbers is the list of prime numbers. Following 11, the next two numbers in the list are 13 and 17.
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.
15... you're dividing by 2 each time.
