Answer:

The sequence follows a +2 and -2 pattern.

Explanation:

As you can see that the series start with 16 and if you look closely, there's a gap of 12 between the first and the third digit. Similarly, there's a gap of 14 digits between the third and the fourth digit, thus +2.

At the same time the correlation between the second and the fourth digit shows a differnece of 7. Similarly, the fourth and the sixth place (?) should be a deficit of 5 and hence, -2.

These sequence follows a varied sometimes non-recurring patterns just to tingle with you brain.

Cheers.
