The same sequence may be defined three ways: 1) f(x) = 1/4 x + 1/4 for x = {1, 2, 3, ...}, 2) a1 = 1/2 and an + 1 = an + 1/4 for n = {1, 2, 3, ...} and 3) an = 1/4 + 1/4 (n − 1) for n = {1, 2, 3, ...}.

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?

Identify a1 and r for the geometric sequence an= -256(-1/4) n-1
