Answer:
Pressure is the force exerted per unit area.
Pressure = Force/area
Clearly from formula pressure is directly proportional to force applied.
Therefore on increasing force pressure increases and on decreasing force pressure decreases.

Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid.
The pressure exerted on a surface by an object increases as the weight of the object increases or the surface area of contact decreases. Alternatively the pressure exerted decreases as the weight of the object decreases or the surface area of contact increases.
