The speed ratio and the train value, in a simple train of gears, is independent of the size and number of intermediate gears. These intermediate gears are called idle gears, as they do not affect the speed ratio or train value of the system.

Explanation:
In a gear train, the motion of the driven gear is determined by the arrangement and number of gears in the train. The gear train consists of a driving gear which is connected to a power source and a driven gear which receives the motion from the driving gear. The motion of the driven gear depends on the number of idle gears in the train.
Simple Gear Train:
A simple gear train consists of two gears connected by a common shaft. The driving gear is connected to the power source and the driven gear receives the motion from the driving gear. In a simple gear train, the number of idle gears is the number of gears in the train minus 2 (since the driving and driven gears are engaged).
Odd Number of Idle Gears:
If the number of idle gears in a simple gear train is odd, it means that there is an odd number of gears in the train excluding the driving and driven gears. In this case, the motion of the driven gear will be the same as that of the driving gear.
Reasoning:
The motion of a gear is determined by its number of teeth. When two gears are engaged, the driven gear rotates in the opposite direction compared to the driving gear. However, when there is an odd number of idle gears, the rotation direction is reversed for each idle gear.
For example, if the driving gear rotates clockwise, the first idle gear will rotate counterclockwise, the second idle gear will rotate clockwise, the third idle gear will rotate counterclockwise, and so on. As a result, the overall motion of the driven gear will be the same as that of the driving gear.
Conclusion:
In a simple gear train, if the number of idle gears is odd, the motion of the driven gear will be the same as that of the driving gear. This is because the rotation direction is reversed for each idle gear, resulting in the same overall motion for the driven gear.
