This road sign was found on OR Hwy-35 between Government Camp and Hood River in Oregon.

The road sign says...

+---------------------+ | <- Govt. Camp 16 | | Hood River 26 -> | +---------------------+ | Hwy-35 | +---------------------+the numbers are: 16 26 35 the off-by-one math is: sqrt(35 - 26) + 1 = sqrt(16) observe... 35 - 26 = 9 sqrt(9) = 3 3 + 1 = sqrt(16) = 4## Update::2008.02.02

If we borrow one from 26 and add it to 35, we get three square numbers.

the numbers are: 16 25 36 the counting math is: sqrt(16), sqrt(25), sqrt(36) observe... sqrt(16) = 4 sqrt(25) = 5 sqrt(36) = 6 more math: avg(sqrt(16), sqrt(36)) = sqrt(25) observe... avg(4, 6) = 10/2 = 5
