## Tiling a 2 × n Checkerboard with L-Shaped Pieces### Problem OverviewYou have a large \(2 \times n\) checkerboard and you aim to cover its \(2n\) squares using the available pieces. Let \(a_n\) represent the number of legal tilings of a \(2 \times n\) board. The pieces used are gray L-shaped tiles that cover 3 squares. Below is an example of a legal tiling:(Insert diagram: A rectangular board with L-shaped tiles covering specific areas.)### Tasks#### (a) Initial Values- Determine the initial values \(a_1\), \(a_2\), \(a_3\).- Note that not all board sizes can be fully covered, so some values may be zero.#### (b) Recurrence Relation- Find a recurrence relation satisfied by the sequence \(a_n\).#### (c) Generating Function- Identify the rational function that serves as a generating function for these numbers.#### (d) Exact Formula- Derive an exact formula for \(a_{3m}\) for \(m = 1, 2, 3, \ldots\).### Diagram ExplanationThe given diagram showcases a \(2 \times 3\) board covered by two L-shaped tiles. Each L-shaped tile covers precisely 3 squares, illustrating a possible configuration where the board is completely tiled without any overlaps or gaps. When devising solutions, consider the orientation and placement of these L-shaped tiles as you explore the possible arrangements for various board lengths.
