Hello, HNCMATHS!
We don't need any fancy formulas, do we?A lathe has a range of six speeds.
The lowest begins at 81 RPM and the highest begins at 954 RPM.
Determine the six speeds if they are arranged in arithmetic progression.
We have six equally-spaced numbers:. .
The range is: .
So the numbers are spaced: . apart.
The six speeds are: .
