Nore. When any even number of terms differ by Arithmetical Progression, the sum of the two extremes will be equal to the two middle numbers, or any two means equally distant from the extremes : As 2, 4, 6, 8, 10, 12, where 6+8, the two middle numbers are = 12+2, the two estremes, and = 10+4 the two means = 14. Woen the number of terms are odd, the double of the middle terin will be equal to the two extremes, or of any two means equally distant from the middle term : As 1, 2, 3, 4, 5, where the double of 3=5+1=2+4=6. In Arithmetical Progression five things are to be observed, viz. The first term. The last term. The numb'r of terms. The surn of all the terms. I. 2. The first, fecond and third term given to find the fifth. RULE. Multiply the sum of the two extremes by half the number of terms, or multiply half the sum of the two extremes by the whole number of terms, the product is the total of all the terms. How many 2.
