сЕКъДА 401 - RULE. Divide the difference of the extremes by the common difference, and add 1 to the quotient. EXAMPLES. 1. The extremes are 7 and 43, and the common difference is 4 ; what is the number of terms ? Ans.
сЕКъДА 428 - A circle is a plane figure bounded by a curved line, called the circumference, every point of which is equally distant from a point within called the center.
сЕКъДА 35 - The number thus added to itself, or the number to be multiplied, is called the multiplicand. The number which shows how many times the multiplicand is to be taken, or the number by which we multiply, is called the multiplier.
