The next number is 70.
The sequence is the central spine numbers of Pascal's Triangle (see related link and related question below).

what are the next 2 numbers in this sequence: 20 , 1 ,18 ,4 ,9 ,1
The sequence appears to be decreasing by 2, then increasing by 5, and then decreasing by 2 again. Following this pattern, after 19, the next number would follow the same decrease of 2. Therefore, the next number in the sequence is 17.

To get the next number in the sequence, you simply multiply by 26*2=1212*2=2424*2=4848*2=96

what are the next 2 numbers in this sequence: 20 , 1 ,18 ,4 ,9 ,1
The next number in the sequence is 27.
44 this is based on a sequence of doubling the initial number then adding 2 to that result.
The sequence appears to be decreasing by 2, then increasing by 5, and then decreasing by 2 again. Following this pattern, after 19, the next number would follow the same decrease of 2. Therefore, the next number in the sequence is 17.
The next number in the sequence is 20. This is because the sequence is decreasing by 2, then decreasing by 6, then decreasing by 2, and then decreasing by 6. So, the next step would be to decrease by 2 again, resulting in the number 20.
You are multiplying each number in the sequence by -2. Therefore, the next number in the sequence after 32 is -64.
