Consider the arithmetic sequence 6, 13, 20, 27, 34, . . . . Let u1 represent the first term.
a. Write a recursive formula that describes this sequence.
b. Write an explicit formula for this sequence.
c. What is the slope of your equation in 19b? What relationship does this have to the arithmetic sequence?
d. Determine the value of the 32nd term. Is it easier to use your formula from 19a or 19b for this?
