Plugging 2 into this equation gives 11/3 or 3.666....
Is there an error in what Scintill showed earlier to show an answer of exactly 3.8?

[num1, num2]: highestnum
1,1: 1 2,1: 2 3,1: 3 4,1: 4 5,1: 5
1,2: 2 2,2: 2 3,2: 3 4,2: 4 5,2: 5
1,3: 3 2,3: 3 3,3: 3 4,3: 4 5,3: 5
1,4: 4 2,4: 4 3,4: 4 4,4: 4 5,4: 5
1,5: 5 2,5: 5 3,5: 5 4,5: 5 5,5: 5
[amount of combinations]
5^2 = 25
[number's amount of occurrences]
1: 1
2: 3
3: 5
4: 7
5: 9
[weight of numbers]
1: 1 * 1 = 1
2: 3 * 2 = 6
3: 5 * 3 = 15
4: 7 * 4 = 28
5: 9 * 5 = 45
[sum of weights]
1 + 6 + 15 + 28 + 45 = 95
[average] = [sum of weights] / [amount of combinations]
average: 95 / 25 = 3.8
using your formula:
0.5^(1/2)*4+1 = 3.8284~~~
