Six speeds

A drilling machine is to have 6 speed ranging from 50 to 750 revolution per minute. If the speed forms a geometric progression, determine their values.

Result

a1 =  50 rpm
a2 =  85.939 rpm
a3 =  147.71 rpm
a4 =  253.88 rpm
a5 =  436.362 rpm
a6 =  750.007 rpm

Solution:

Solution in text a1 =
Solution in text a2 =
Solution in text a3 =
Solution in text a4 =
Solution in text a5 =
Solution in text a6 =
