Page 154 - GEOMETRICAL PROGRESSION. A series of three or more numbers, increasing by a common multiplier, or decreasing by a common divisor, is called a geometrical progression. If the greater numbers of the progression are to the right, the progression is called an ascending geometrical progression, but, on the contrary, if they are to the left, it is called a descending geometrical progression. The number by which the progression is formed, that is, the common multiplier, or divisor, is called the ratio.
Page 147 - RULE. 1 . Separate the given number into periods of three figures each, by putting a point over the unit figure and every third figure bejond the place of units.
