Describe the pattern below. What are the next two numbers? 1.64,3.28

see explanation

Step-by-step explanation:

note that 3.28 = 2 * 1.64

This could be a geometric sequence with common ratio r = 2

To obtain the next term multiply the previous term by 2

3.28 * 2 = 6.56

6.56 * 2 = 13.12

1.64, 3.28, 6.56, 13.56 ← first 4 terms in sequence
