### 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.

7 + 8 equals 15

subtract 5 from 15 gives 10

8 + 10 equals 18
18 - 5 equals 13

Funville is 13 miles away
