The displacement and the increase in the velocity of a moving particle in the time interval of \( t \) to \( (t+1) \, \text{s} \) are \( 125 \, \text{m} \) and \( 50 \, \text{m/s} \), respectively. The distance travelled by the particle in \( (t+2)^{\text{th}} \, \text{s} \) is________ \( \text{m} \).
