This bus stop sign was located on 5th Street in Tempe near College Avenue.

the numbers are: 48 56 62 65 66 68 76 92 the math is: root^{(65 - 62)}(56 - 48) + 68 - 66 = sqrt(92 - 76) root^{3}(8) + 68 - 66 = sqrt(16) 2 + 68 - 66 = 4The math for this problem became clear by looking at the difference between adjacent pairs of numbers.

56 - 48 = 8 65 - 62 = 3 68 - 66 = 2 92 - 76 = 16 intermediate numbers: 8 3 2 16 observed that 2 cubed is 8 and that 16 is 4 squaredThis bus stop sign cannot be submitted to RoadSignMath.com because there was another side to the sign that contained the phone number:
