Tried Mohanaji's pattern on the paper with colored pencils.
I've used one more level other than Mohanaji. Here is the level of complexity:
n = 0, no of lines = 0, no of dots = 1
n = 1, no of lines = 1 (1 green), no of dots = 5
n = 2, no of lines = 5 (4 green, 1 pink), no of dots = 25
n = 3, no of lines = 9 (4 green, 4 pink, 1 blue), no of dots = 61
n = 4, no of lines = 13 (4 green, 4 pink, 4 blue, 1 purple), no of dots = 113
n = 5, no of lines=17, (4 green, 4 pink, 4 blue, 4 purple, 1 orange) no of dots = 181
Thank you for the workout, Mohanaji.
