What are the first three terms of the arithmetic sequence represented by the number of shaded tiles and the common difference?
The first three terms are [ ], [ ], and [ ], and the common difference is.
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.
