Please answer fast I will rate for you sure....

A drill used in the manufacture of engine parts
is designed to have seven speeds.
The range of hole sizes anticipated is from
6mm to 25mm.You have been asked to
generate answers for the seven spindle speeds
(rev/min) given that the cutting speed, V is
20m/min.
These spindle speeds are to be arranged in:
a) arithmetic progression
b) geometric progression
