Analytical:1, n line divides the plane into the number of regions: F (N) =f (n-1) +n=n (n+1)/2+1;2, divides the space to the most region number time, the nth plane and the front (n-1) plane intersects, and does not have the three sides collinear, therefore this plane and the front (n-1) plane has (n-1) the intersection line. The intersection divides the nth plane into an F (n-1) region, so the plane divides the original space into two, increasing the F (n-1) space, the recursive formula: g (n) =

Analytical:1, n straight line to cut the plane into the number of areas: F (N) =f (n-1) +n=n (n+1)/2+1;2. When the space is cut to the maximum number of regions, the nth plane intersects with the front (n-1) plane. And there is no three-side collinear, so the plane and the front (n-1) plane has (n-1) intersection line.These intersection lines cut the nth plane into an F (n-1) region. So this plane divides the original space into two, adding F (n-1) space, recursion formula: G (n) =g (n-1) +f (n-
