The information provided is incomplete. Please provide the number of shaded tiles and the common difference in order to determine the first three terms of the arithmetic sequence.
term 1: 12 shaded tiles
term 2: 16 shaded tiles
term 3: 20 shaded tiles
In this arithmetic sequence, the common difference is 4, as the number of shaded tiles increases by 4 from one term to the next.

Therefore, the first three terms of the arithmetic sequence are:
1st term: 12 shaded tiles
2nd term: 12 + 4 = 16 shaded tiles
3rd term: 16 + 4 = 20 shaded tiles

So, the first three terms are 12, 16, and 20, with a common difference of 4.
