Answer 2

The ratio of two spindle speeds is constant in geometric progression.​

• In geometric progressions, the proportion between the two consecutive spindle speeds remains constant. The step ratio or progression ratio is the proportion between two consecutive spindle speeds when they are structured in geometric succession.
• In harmonic progressions, the gap between the reciprocals of two successive spindle speeds is constant. Harmonic Progression occurs when the reciprocals of a series of numbers are in Arithmetic Progression.
• In arithmetic progressions, the gap between two succeeding spindle speeds is constant. The sum of a finite arithmetic progression is an arithmetic series.
