Julianthemath's number 2

This will be my next discovery (since the other was been discovered)

So, it is the sum of 2 consecutive square numbers, minus the combined square root.

This :
1 + 4 = 5
1 + 2 = 3
5 - 3 = 2 - a Julianthemath number.

Another :
4 + 9 = 13
2 + 3 = 5
13 - 5 = 8

3rd Julianthemath number :
9 + 16 = 25
3 + 4 = 7
25 - 7 = 18

So, the Juianthemath sequence is: 2, 8, 18, 32, etc.

Isn’t this simply a[sub]n[/sub] = 2n[sup]2[/sup] ?
