Find Signal x(n) - Hint for Solving x(n)+x(-n)

[robert25pl]

I have to find the signal if x(n) = nv(n-1) for -infinite < n < + infinite

x(n)+x(-n)

Can I get hint with this problem so I can do rest of them. Thanks

x(n) is a vector function where n is all the intergers from -infinity to +infinity. nv(n-1) is n*v(n-1) which is the multiplication of two vectors. Again n is all integers from -infinity to +infinity and v(n-1) is the vector function v(n) after all the elements have been shifted over one position to the right.

At least that's what it looks like form my position.
