...centre of our system of arithmetical notation, and is the arithmetical mean between the extremes of I and 9, 2 and 8, 3 and 7, and 4 and 6. Then : One pair...of numbers will be 25 and 6-25; and the other pair will be 19-53125 and 8; and v/25~x 6-25 = J19-53125 x 8= ^I56-25 = 12-5. Hence: The mean proportional... | |
