The answer is: 9, 12, 15.
See, first there is 3, 4, and 5. Then 3 is multiplied by 2 to make 6. 4 by 2 to make 8. and 5 by 2 to make 10.
They're ALL multiplied by the same number 2.
So to get the third set of numbers, you have to multiply them ALL by the same number- 3.
Thus, 9, 12, and 15.

3^2+4^2=9+16=25 = 5^2
6^2+8^2=36+64=100=10^2
9^2+12^2=81+144=225=15^2, so third set is 9,12,15
