[tex]a,b)\; \displaystyle U_n = n^2 \to \boxed{\boxed{U_4,U_5,U_6 = 4^2,5^2,6^2 = 16,25,36}}\\\\c)\; U = \{1,5,13\} = \{0^2+1,1^2+2^2,2^2+3^2\}\\\to U_n = (n-1)^2+n^2 = 2n^2-2n+1\\\boxed{\boxed{ U_4,U_5,U_6 = 25,41,61 }}[/tex]
2.
[tex]a) \;U_n = 2n\to \boxed{\boxed{U_{6},U_7,U_8 = 2\cdot 6,2\cdot 7,2\cdot 8 = 12,14,16}}\\ \\b) \;U_n = 2n-1\to \boxed{\boxed{U_{6},U_7,U_8 = 2\cdot 6-1,2\cdot 7-1,2\cdot 8-1 = 11,13,15}}\\\\c) \;U_n = n^2\to \boxed{\boxed{U_{6},U_7,U_8 = 6^2,7^2,8^2 = 36,49,64}}\\ \\d) \;U_n = 10+5n\to \boxed{\boxed{U_{6},U_7,U_8 = 40,45,50}}\\ \\[/tex]
