Among the following propositions, the true ones are numbered \_\_\_\_\_\_.
\\(①\\) In space, if \\(m\\) and \\(n\\) are two non-coincident lines, and \\(α\\) and \\(β\\) are two non-coincident planes, with \\(α⊥β\\), \\(α∩β=n\\), and \\(m⊥n\\), then \\(m⊥β\\);
\\(②\\) The closer the absolute value of the correlation coefficient \\(r\\) is to \\(1\\), the stronger the linear correlation between two random variables;
\\(③\\) Using the Qin Jiushao algorithm to calculate the polynomial \\(f(x)=208+9x^{2}+6x^{4}+x^{6}\\) at \\(x=-4\\), the value of \\(v_{2}\\) is \\(22\\);
\\(④\\) If a line through the focus of the parabola \\(y^{2}=4x\\) intersects the parabola at points \\(A\\) and \\(B\\), then there are exactly two lines that make the sum of their x-coordinates equal to \\(4\\).
