A. Find the indicated number of geometric means between each pair of numbers 1. 16 and 81 2. 256 and 1 3. -32 and 4 NENW 4. 3 and 3 5. 2xy and 16xy* B. The geometric mean between the first two terms in a geometric sequence is 32. If the third term is 4, find the first term. C. Insert a geometric mean between k and - D. If 2 and 3 are two geometric means between m and n, find the values of m and n. E. Three positive numbers form a geometric sequence. If the geometric mean of the first two numbers is 6 and the geometric mean of the last two numbers is 24, find the three numbers and their common ratio
