Answer:

v = (15)/(2)

Explanation:

$1. \: v = (2 * 2 + 1)/(2) * 2 * 1 (1)/(2) \\ 2. \: v = (4 + 1)/(2) * 2 * 1 (1)/(2) \\ 3. \: v = (5)/(2) * 2 * 1 (1)/(2) \\ 4. \: v = (5)/(2) * 2 * (1 * 2 + 1)/(2) \\ 5. \: v = (5)/(2) * 2 * (2 + 1)/(2) \\ 6. \: v = (5)/(2) * 2 * (3)/(2) \\ 7. \: v = 5 * (3)/(2) \\ 8. \: v = (5 * 3)/(2) \\ 9. \: v = (15)/(2)$
