DIRECTIONS: Show all of your work and write your answer in the space provided. MODIFIED TRUE/FALSE: If the statment is true, write true in the blank. If it is false, replace the underlined word(s) with the word(s) that will make the statement true. 1. A series that tends toward a single number is called a divergent series. 2. A series is the product of the terms in a sequence. 3. A(n) alternating geometric sequence switches between positive and negative values....
