Lesson 1 Summary

A sequence can be thought of as an ordered list of elements. To define the pattern of the sequence, an explicit formula is often given, and unless specified otherwise, the first term is found by substituting 1 into the formula. Lesson 1 Exit Ticket

1. Consider the sequence given by a "plus 8" pattern: 2, 10, 18, 26, .... Shae says that the formula for the sequence is f(n) = 8n + 2. Marcus tells Shae that she is wrong because the formula for the sequence is f(n) = 8n - 6.
a. Which formula generates the sequence by starting at n = 1? At n = 0?
b. Find the 100th term in the sequence.

2. Write a formula for the sequence of cube numbers: 1, 8, 27, 64 ....
