Douglas Lin · Answer 1

The given sequence is a geometric sequence. The property of geometric sequence is that each term is multiplied by a specific number known as "common ratio" to get the next term. In this case the common ratio is 1/2.

2 x 1/2 = 1

1 x 1/2 = 1/2

1/2 x 1/2 = 1/4

and so on ...
