The sum of the first n terms of a linear sequence is \(S_{n} = n^{2} + 2n\). Determine the general term of the sequence.

If \(2\log_{4} 2 = x + 1\), find the value of x.

Find the range of values of x for which \(2x^{2} + 7x - 15 > 0\).

If \(f(x) = 2x^{2} - 3x - 1\), find the value of x for which f(x) is minimum.

The sum of the first n terms of a linear sequence is \(S_{n} = n^{2} + 2n\). Find the common difference of the sequence.
