    What reason do you have to think there IS a pattern?

    Here is a news flash for them:
    The largest collection of integer sequences available says that no such sequence is known to exist.
    Check it out at: The On-Line Encyclopedia of Integer Sequences

    Look at the common difference for if it was a geometric or arithmetic sequence, or even a recursive formula there would have to be a distinguishable pattern

    just look at the differences:

    \frac{1}{16}=0.0625

    \frac{20}{1}=1

    \frac{20}{20}=1

    \frac{5}{20}=0.25

    \frac{18}{5}=3.6

    As you can see there is no common difference, and no possible way for it to be an arithmetic or geometric progression.There is also no way to make a recursive formula for the sequence.
