- 13 and 14 could be swapped, randomized or otherwise modified so they are not exactly as in the book.
- 15 could be modified further. Maybe even randomized?
- Randomize 23.
- Make 28 and 30 into webwork (even if not randomized).
- Randomize 1.
- Make last problem into ww.
- 2 can be made into a randomized mc problem easily.
In general, this section needs more WW. Even if I make up brand new problems, there need to be some. Perhaps as simple as asking for a_8 for recursive or closed formulas.
- Problem 3 as ww?.
- And 4. Webwork can do sequences. Look at 2.2.2 as example.
- None of these appear to be randomized/different. Do some!
- Problem 5 could be made into ww as follows: Find a sequence with a_0 = 1 and second difference...., what is a_5?
- lots still need to be randomized
- Only first three problems are randomized.
