Average Sudoku (Daily Sudoku League #101)

This Average Sudoku I prepared for Sudoku Mahabharat Episode 7 themed Converse. Hopefully this will be good practice for this Sudoku Mahabharat Episode.

This Average Sudoku is my 101st contribution for The League of Extraordinary Ladies and Gentlemen.

Rules of Average Sudoku

Classic Sudoku Rules apply. Additionally if the number in a cell equals the average of its two horizontal neighbours then the cell is marked with a horizontal line. If the number in a cell equals the average of its two vertical neighbours then the cell is marked with a vertical line. All possible lines are marked.
