BARS::BARS Along Lake Mary Road [northern Arizona]

The road signs along Lake Mary Road were brown with white lettering and most of them contained at least three numbers.


Sign #0

+--------------------+
| Fooville         4 |
| Gootown          5 |
| Blahview        11 |
+--------------------+

   the numbers are:  4  5  11

   the math is:  sqrt(11 + 5) = 4
Sign #1

+--------------------+
| Fooville         7 |
| Gootown          8 |
| Blahview        10 |
+--------------------+

Pretend the road sign had a fourth line that gave the mileage to Funland. Determine what the mileage to Funland should be.

+--------------------+
| Fooville         7 |
| Gootown          8 |
| Blahview        10 |
| Funland         ?? |
+--------------------+

   the "adder" is incremented by one

        7 + 1 equals  8
        8 + 2 equals 10         [1 + 1 is 2]
       10 + 3 equals 13         [2 + 1 is 3]
       ?? + ? equals ??         [? + 1 is ?]

       Funville is 13 miles away.

       or...

   the "adder" is doubled (i.e. times 2)

        7 + 1 equals  8        
        8 + 2 equals 10         [1 x 2 is 2]
       10 + 4 equals 14         [2 x 2 is 4]
       ?? + ? equals ??         [? x 2 is ?]

       Funville is 14 miles away.

   other patterns

       7 + 8 equals 15

       subtract 5 from 15 gives 10
       
       8 + 10 equals 18
       18 - 5 equals 13

       Funville is 13 miles away
