The road sign says...

+------------------+ | Longmont 5 | | Lyons 16 | | Estes Park 36 | +------------------+ the numbers are: 5 16 36 the math is: avg(sqrt(16), sqrt(36)) = 5 observe... sqrt(16) = 4 sqrt(36) = 6 avg(4, 6) = (4 + 6) / 2 = 10 / 2 = 5 basic counting: sqrt(16), 5, sqrt(36) = 4, 5, 6 off-by-one math: sqrt(36) = 5 + sqrt(sqrt(16)) + (-1) off-by-one Pi math: (16 + 5) / sqrt(36) = 21 / 6 (21 + 1) / (6 + 1) = 22 / 7 = Pi (3.14) [exercise] find more math
