For each natural number k. Let `C_(k)` denotes the circle with radius k centimetres and centre at origin. On the circle `C_(k)` a particle moves k centrimetres in the counter-clockwise direction . After completing its motion on `C_(k)` the particle moves to `C_(k+1)` in the radial direction . The motion of the particle continue in this manner. The particle starts at ( 1,0). If the particle crosses the positive direction of the X -axis for the first time on the circle `C_(n)`, then `n ="__________________"`.

For each natural number k, let C_k denotes the circle radius k centimeters in the counter-clockwise direction.After completing its motion on C_k , the particle moves to C_[k+1] in the radial direction.

For each natural number k, let C_k denotes the circle with radius k units and centre at the origin. On the circle C_k , a particle moves k units in the counter clockwise direction. After completing its motion on C_k , the particles moves to C_(k + l) , in some well defined manner, where l gt 0 . The motion of the particle continues in this manner.
