Here is a

**news flash for them**:

The largest collection of integer sequences available says that no such sequence is known to exist.

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:

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.
