If 1/a , 1/b and 1/c are in Arithmetic Progression, then which of the following is also true?

1) (b + c)/a, (c + a)/b and (a + b)/c are also in arithmetic progression for all values of a, b and c.
2) (b + c – a)/a, (c + a – b)/b and (a + b – c)/c are also in arithmetic progression when a + b + c is not 0.
3) (b + c)/a, (c + a)/b and (a + b)/c are in geometric progression for all values of a, b and c.
4) Both (1) and (2).
