Keep looking () Larry Barrett
Now that the sun is up I can see 8 lines to the left, 9 lines to the right.
On the left side I am looking for values of x where at least two of the series (x, 4x, 7x, 10x, 13, 16x) are integers. Easy when x is an integer, but harder when x can be any fraction.
Similar problem on the right hand side, except the series is (2x, 5x, 8x, 11x, 14x, 17x, 20x).
