6. You visit the Royal Gorge Bridge near Canon City, Colorado. When walking across the bridge you nudge a small stone off the bridge deck and watch it fall. The distance the stone drops is 16 feet the first second, 48 feet the next second, 80 feet the third second, and so on in an arithmetic sequence.

Part I: How far does the stone fall during the fifth second? Find and use the explicit formula.

Part II: The table below shows the values in the sequence you already know. Use the explicit formula to complete the table for the first 10 seconds.
