Practice Problems

Try them, get help one step at a time, then print how it went.

Practice: try it, then get help one step at a time

Naming terms, the two notations, domain and range in words, and deciding whether a list adds, multiplies, or neither. Hint gives a nudge, Show next step shows one worked step at a time, Reveal answer checks, and Hide help / start over clears the card.

My results

Finished the practice? Print a page that shows each question, what you typed or chose, the correct answer, and how it went. Good for showing a teacher or keeping in a folder.

On paper or an index card. Use the math word and the plain-English word.

  1. In 4, 11, 18, 25, ... what are a1 and a3, and what is the next term?
  2. Why is a sequence a function? Name the input and the output.
  3. A theater has 25 rows with 60, 68, 76, ... seats. What is the domain, and why are there no decimals in it?
  4. Adds, multiplies, or neither: 5, 10, 20, 40? 1, 4, 9, 16?

  1. a1 = 4, a3 = 18, next term 32.
  2. Each term number (input) gives exactly one term (output).
  3. The row numbers 1 to 25. There is no row 2.5.
  4. Multiplies (geometric, times 2). Neither (the square numbers).
