4. CLASSIC PROBLEM - A traveling salesman (selling shoes) stops at a farm in the Midwest. Before he could knock on the door, he noticed an old truck on fire. He rushed over and pulled a young lady out of the flaming truck. Farmer Brown came out and gratefully thanked the traveling salesman for saving his daughter’s life. Mr. Brown insisted on giving the man an award for his heroism.
   So, the salesman said, "If you insist, I do not want much. Get your checkerboard and place one penny on the first square. Then place two pennies on the next square. Then place four pennies on the third square. Continue this until all 64 squares are covered with pennies." As he’d been saving pennies for over 25 years, Mr. Brown did not consider this much of an award, but soon realized he made a miscalculation on the amount of money involved.
   1. How much money would Mr. Brown have to put on the 32 ^nd square?

Problem: Using the index of a sequence as the domain and the value of the sequence as the range, is a sequence a function?

Which one of the basic functions (linear, quadratic, rational, or exponential) is related to the arithmetic sequence?

Which one of the basic functions (linear, quadratic, rational, or exponential) is related to the geometric sequence?

Give at least two real-life examples of a sequences or series. One example should be arithmetic, and the second should be geometric.
