In this module, you will be introduced to infinite sequences and series. The module content is split into two lessons.

**Project 5:**

All sequences in this project are assumed to begin with k=1, unless otherwise noted.

Recall piecewise-defined functions such as

- Write out the first 12 terms of the “piecewise-defined sequence”

- Write out the first 12 terms of the “piecewise defined sequence”

Each of the “pieces” in #1 and #2 are called a subsequence of its respective sequence. Note that each of the four subsequences converges but while the sequence {a_{k}} in #1 converges to zero, the sequence {a_{k}} in #2 diverges since the subsequence consisting of the odd-numbered terms converges to 1 and subsequence consisting of the even-numbered terms converges to -1 - Find a piecewise formula definition of the sequence 0, 1, 0, 2, 0, 4, 0, 8, 0, 16, 0,…
- Do a search on the internet to find some reliable web site or page that states and discusses the Bolzano-Weierstrass Theorem. Write at least one standard page (“typed,” double-spaced, and with no more than 1.25 inch margins) that discusses how the Bolzano-Weierstrass Theorem applies to the sequences you dealt with in #1 and #2, and how the Bolzano-Weirstrass Theorem relates the Bounded Monotonic Sequence Theorem covered in lesson 1 of this module.
