Consecutive terms in the sequence are being divided by -2. Therefore, -1 / -2 = 1/2 or 0.5.
2,2,2 12222 122222 1222222
next terms in the sequence one eighth one fourth one half: 1/8, 1/4, 1/2, 1, 2, 4, 8,... (multiply by 2)
what are the next 2 numbers in this sequence: 20 , 1 ,18 ,4 ,9 ,1
2, 1, 0.5 Half the term each time.

13 This is because each term of the sequence is determined by adding the 2 previous terms of the sequence. This particular sequence is called the Fibonacci Sequence, and has special properties. See related link.
The Fibonacci sequence adds the 2 previous terms to find the next one. For instance: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55... etc.
what are the next 2 numbers in this sequence: 20 , 1 ,18 ,4 ,9 ,1
They are: 10 and 16
2, 1, 0.5 Half the term each time.
This is a Fibonacci sequence with alternate terms omitted. The first two numbers in the Fibonacci sequence are 0 and 1, and each subsequent number is the sum of the previous two. (0),1,(1),2,(3),5,(8),13,(21),34,(55),89 The bracketed terms are the omitted terms. The next number would thus be 89
Which sequence? Oh, that one! The first three terms are 1, 2 and 72.
