6-1 Recursive and Explicit Form of a Sequence
ClassPad supports use of three types of sequence expressions: a

Generating a Number Table
In addition to an ordered pair table, you can create a sequence table with column(s). This helps you determine if
the sequence is an arithmetic sequence, geometric sequence, progression of difference, or Fibonacci sequence.
3 = 2 + 1
3 = 7 − 4
Fibonacci Sequence Table Ordered Pair Table Arithmetic Sequence Table
3 = 18 ÷ 6
