Quick start
- Choose Arithmetic, Geometric, or Fibonacci.
- Enter the first values requested by that mode.
- Choose how many terms to generate.
- Press Generate sequence and review the rule and next term.
Choosing a sequence type
Arithmetic sequences add the same difference each time. Geometric sequences multiply by the same ratio each time.
Fibonacci-style sequences add the previous two terms to make the next term.
Checking a pattern
Use the first two values to define the pattern, then compare the generated terms with the sequence in your notes or assignment.
Copy the result when you need to paste the sequence into another document.
