Identify the sequence as arithmetic, geometric, or neither. 1.6, 0.8, 0.4, 0.2, . . a. arithmetic b. geometric c. neither

The sequence is a geometric sequence, because there is no common difference between the 4 terms. We would multiply by  to get to the next term, therefore proving it to be a geometric sequence.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

That's the answer and the the information
