Arithmetic sequence - the sequence has a common difference between any two consecutive numbers.

Example:  2, 4, 6, 8, 10, ...  (The difference is 2)

Geometric sequence - a sequence where any two consecutive number has a common ratio.

Given: 4, 16, 64, 256 ... (divide any two consecutive sequence.  If 
                                          they have common ratio, then it's geometric)

16÷4 = 4
64÷16 = 4
256 ÷ 64 = 4

ANSWER:  The common ratio is 4.  Since it has a common ratio, the sequence is geometric.
