```
```   the numbers are:  147  51  2  1/4  10  147  51  202  1/4  148

the math is:
sqrt(202-147-51)*(10+sqrt(1/4)+sqrt(1/4)) = 147-51-148/2

observe...
left-side:
202 - 147 - 51 = 4
sqrt(4) = 2
sqrt(1/4) = 1/2
10 + sqrt(1/4) + sqrt(1/4) = 10 + 1/2 + 1/2 = 11
2 * 11 = 22
right-side:
147 - 51 = 96
148 / 2 = 74
96 - 74 = 22

[exercise--solve for 'n']
sqrt(202-147-51)*(10+sqrt(1/4)+sqrt(1/4)) = 147-51-148/n
