For a particle moving along the \( x \)-axis, mark the correct statement(s).
(1) If \( x \) is positive and is increasing with the time, then average velocity of the particle is positive.
(2) If \( x \) is negative and becoming positive after some time, then the velocity of the particle is always positive.
(3) If \( x \) is negative and becoming less negative as time passes, then the average velocity of the particle is positive.
(4) If \( x \) is positive and is increasing with time, then the velocity of the particle is always positive.
